Large uterus... twins?

post #1 of 17
Thread Starter 
From what I recall of my reading, the uterus pops up above the pubic bone somewhere around 12-13 weeks and reaches the navel at 20 weeks, give or take. While I know that "big" discrepancies are pretty normal toward the end when baby is getting big and a simple position change can make the difference between 3 and 5cm or more... what about when the baby is only an inch long?

I'm not exactly sure of conception, but I usually ovulate around day 21-23 (except on the month I conceived my son, where for some reason I ovulated on day 17 for the first and only time in my life). I was lazy charting the month of this baby's conception, and only recorded cervical mucous once when I thought it was eggwhite-y, on day 28.

So, using the range of day 17 through day 28, I'm somewhere around 10 to 13 weeks pregnant, probably more like 12 given my usual ovulation time. I've felt light flutters for the last week, and I was feeling my daughter around 11 weeks so that matches up.
The only part that really isn't making sense is that for the last 1-2 weeks I've been trying to see if I could feel the top of my uterus under my pelvic bone. It all felt pretty hard, and I thought for sure it was just scar tissue from my c-section... but upon doing a dual feel (inside and out at once so I can bounce my uterus around and feel roughly how big it is) I realized the reason I haven't been feeling it down there is because it isn't down there: it's about five inches above my pubic bone and just about four or five fingerwidths below my navel. That's pretty large for 10-13 weeks, isn't it?

Barring the idea that my *only* postpartum period was not a period, which would put me 18+ weeks pregnant (which would not match up in a big, big way) ... I'm starting to wonder about twins.

Is this plausible at all based on the uterine measurement? Any suggestions as to what else might be throwing my measurement off so much?

(FYI, I'm also tiny and thin, if that makes a difference).

I've been told the uterus can "ride high" after a cesarean, or that you can show earlier, and while I do notice my abdomen more slack than the last two times (I was quite fit before the conception of my second child and remained so all the way through. I exercise daily) this really isn't an issue of "showing" but rather my uterus feeling physically quite a big larger than I'd expect...

I think a big uterus CAN be a sign of twins, although not always. It also could be that your uterus had not yet shrunk back to normal size after your angel. It also could be that you are further along than you think. Are you planning to UP/UC or do you have a care provider in mind? It might be a good time to start prenatal visits and see if you find a heartbeat or two. Good luck dear.

If I'm further along than I think, it could only be explained by my first and only postpartum period not being my period and that I was pregnant at that time... which would REALLY not be possible. I know my date range is correct.

I'm UP/UC, but despite being very against it I have considered finding a place that has those "listening devices" on display and doing a quick check for two heartbeats if I still strongly suspect by the time I'm 20+ weeks by my range.

As for uterine shrinking: I had not considered that, but can it really take so many months particularly when a post c-section doctor's visit palpated it at or below my pubic bone?

I would watch it for a while, and if you get to the point where you are feeling overly big/curious/concerned, have it checked out. Do you have people in mind that you would trust to consult with if needed? Twins are a possibility, as is an excess of amniotic fluid or other conditions which merit a visit with a midwife.

I have one midwife I could trust to see if I felt it was needed, as I had her with my daughter (first). However this is my second UP.

I think most women think about twins with nearly every preg. I have nearly every client say SOMETHING about it.

Most measurements level out around 23 weeks or so. I think that until then, assuming your baby is growing normally, I wouldn't worry so much about landmarks but about how much your baby grows in a specific period of time.

Thank you Pam! That's the most useful info I've had so far (I've x-posted this a few places).
This my 7th pg (2 live births) and never even been *close* to being this big (IE, in my last pg 3 months past conception I was measuring three inches smaller than I am now, 2 months past conception). And since the idea of twins at any other time in my life would have horrified me in the kind of way of someone telling me I have cancer, this has got me curious. I was having dreams and hunches before this, (plus bizarre excess weight gain, severe nausea, etc) but with the huge uterus thing I started really wondering.

I think many of us could say that we have seen twins after miscarriage/stillbirth several times... funny how that works. But as I said before, at the early point you are at, I would wait a while and just keep track before wondering about that too much. Good luck mama!

I think I mentioned this somewhere on the DDC but I also have a 'measuring large' uterus although the babe is spot on for my dates.

At 12 weeks I had a hospital appointment (I'm high risk due to blood disorder) They doubted my dates then after to-ing and fro-ing insisted on a scan after not being able to find a hb. It says on my file that I palpated 16-18 weeks but the babe measured 12wks 3 days which is exactly what I had thought based on my cycle.

This is my fourth pregnancy so I don't know if that makes a difference. Depending on how it is lying I can now feel my uterus almost at my belly button sometimes at 18 weeks but it seems to move about a bit and is often lying lower first thing in the morning.

I'm only 5'0 and slim so I can feel my uterus as soon as it appears above my bones very easily.

babs- I have been following my fundal height in astonishment too. I was where you are at least, and now I am one fingertip below my belly button at 15/16 weeks.

I am so not thinking twins... and while a typical mw might worry about dates, etc from measurement alone, I just figure things know how to grow, when to grow, etc, and they will even out after a bit. I am not at all concerned about it. I had a previous c/s and I am built similarly to you (saw a belly pic of you) fwiw. BTW, AmyD (IRL firend of mine... brag brag) was measuring WAY big with her last. She was at belly butoon long before 20 weeks, but then it evened out. I think it is more common IRL than they imply in books.

I would pay more attention to what your baby/babies are telling you than what the tape measure says... Everything will present in its own perfect time.

Other signs of twins are extreme fatigue, and more than usual morning sickness. i was 24 wks when I had an ultrasound because of my age they believed there might be a birth defect. It was only then that they found the twins. Even though I was very very large, I thought they had my due date wrong. But to be honest, other than an ultrasound you can't know for sure. Many times they could not hear two heart beats, only one, so that isn't even a sure bet.
good luck

You have a lot of good things to say lately.

I had strong hunches prior to this due to (don't laugh!) really intense dreams. All my babies told me their names in dreams, told me what they'd look like, and birth details... so I trust my dreams. However it's in my nature to second guess and be wary of taking something as prophetic until it then unfolds.
My morning sickness has been HORRIBLE. With my last pregnancy I didn't so much as burp, and with my first I had it bad but I think I can now say this is worse. I can't tell about the fatigue, I always feel tired, and I've been blaming it on grief.

I didn't think of the fundal height at all until I was just poking around out of curiosity (not looking for it) and all of a sudden realized it was quite huge, which seemed to be the first (if even, apparently, far-fetched) amount of 'physical' to go along with the 'mental', which is why I asked about it.

My thought with you (and what can I *really* tell over the internet?) was that you were looking for some concrete physical evidence to back up what you already know inside... Or think you know, lol.

We prolly all do the same...

Your dreams/intuitions are yours. They are probably right on, IME. Hold them sacred, let them wash over you, through you. Let them mesh with the physical in time. Course sometimes they are not literal, so that is the trick at times, lol.

Many hugs to you as you work through this layer of grief. Remember that grief and love are two sides of the same coin, and you can't have one without the other. Grief is real, it is here to awaken us, pull us into ourselves, get us in touch with our longing. I think we get tired and sometimes sick when we are not embracing it fully... I am glad you can honor it at this time if need be.

I don't know if I told you this already ltp, but my uterus was very big for dates. Belly button height at 14 weeks. So I went for a u/s to rule out twins and it was nothing, and the baby is measuring spot on.

I had morning sickness only with my 2nd, (singleton), and it was soooo icky. With my first and 3rd I was generally fine, and I was pg with twins the first time, so ya just never know...

Just wanted to bump this to say the rate of increase is pretty steady now. measuring 22cm or so (Mar.30th to May 3rd has seen maybe 10cm of growth). Tons of movement, too.

If this is going to even out around 23 weeks would I end up with no growth for a few weeks time? Or would I continue at this rate and be 50cm at 40 weeks with a singleton? -- eek! Two pregnancies haven't left a single stretch mark on my front, but at this rate I think I might actually get them this time
