LOL...how have yoiu measured before? You are on your sixth the same as me. But I've always measured right on at 20 weeks I was at 20 weeks. Before the ultrasound picture started looking twinnish to me I had a "test" I was waiting for. If my uterus was OVER my BB at 16 weeks I was going to be convinced. I'm 14 weeks and it's level with my bellly button...If it continues the way it has been continuing I have no fear that it will be over it in two more weeks. Which is ironically when I'll know for sure because of ultrasound. LOL.
When were your early ultrasounds. Trust me, I've done TONS of reading and it's NOT uncommon for early ultrasounds to miss twins. Also were they performed by a sonographer or were they performed by a doctor as a quick in office look? Apparently that matters too (mine was doc in office) according a friend of a friend who IS a sonographer. (she looked at my picture I posted too, well the unedited with extras one) and she said that it looks like two to her too but sicne she didn't take the picture it's hard to say. LOL....
I've heard of a few people having a couple ultrasounds and still not knowing til 20 weeks.
Anyway...I would say "what does your gut say" but my gut told me when I first was pregnant that it was one baby...and my gut told me two pregnancies before that it was twins and it was one. LMBO....but then when my uterus took off growing like Jack's magic bean, I started to wonder....and with a few other symptoms....and comments...and then discovering that picture where there are other twins that look VERY similar (especially the one on the left)....I'm convinced. LOL...I've been told numerous times that my uterus could just be relaxed from so many babies....but honestly I think the only person that can knokw that for sure is the momma. Basing it off of my previous pregnancies it's way different. I would think it would be gradual, not boom huge. And I've talked to other Grand multipara moms (locally) and they all say the same thing...that it might measure a week or two bigger but six weeks bigger seems a bit strange.
HA...now you are really wondering I bet....sorry! ;)
Well I know I have always measured ahead in the beginning but of course I can't remember when it evened out!! :S I told myself that I wouldn't worry since I had the u/s but then the midwife gave me a really weird look when I was in at my12w appointment, asking me if I was sure of my dates...I was like 'umm, yes...had ultrasound to confirm?' and she was like, well if you hadn't measured ahead before like you say, we'd be talking a lot more about this. I was like, I had 3 ultrasounds...I can't imagine there's one hiding right? But she just gave me a sideways look with a smirk. LOL!! Nice!!
Honestly just like you I was hanging on to the fact that despite checkign I had only found ONE heartbeat (the galloping one, with the sound of valves opening/closing that you get right near baby). I had heard the hb elsewhere but it wasn't the galloping one and I know those are just echoes. Of course my doppler doesn't have a readout so that doesn't help me. I have no idea what the BPM's are and am not accurate enough to count myself I don't think. After finding a second HB (galloping, so not an echo as far as I understand!) on the side I never find anything but placenta sounds has me really wondering if there's another one hiding behind the placenta over there that I haven't been able to find before...it was tricky to find anyway. Both were loud.
As for the ultrasounds, they were quite strange. I had bleeding at 5.5w (a lot) and had an u/s at 6w. They saw only a yolk sac and a subchorionic hematoma...I only got to see a freeze screen of the gestational sac/yolk sac. No hb was visualised, the sonographer wanted to do a vaginal u/s but was afraid to make me bleed again so told me I'd have to come back...and the Dr told me pg was not viable and to wait a few weeks to m/c. I contacted a midwife because I didn't believe him when he told me there should have been a hb even with an abdominal u/s at that stage...she set up antoher u/s at 7w. I got to watch this u/s...the sch looked EXACTLY like a second sac. Unfortunately, the pic they gave me only shows the side view of it so it isn't as obvious as it was on the screen! I am told this is possible for a sch to look like another sac, however it took some digging and moving around just to visualise the one baby and get a flashing HB - not measureable in BPM, embryo measured 7w. So it makes me wonder if there could have been another. I went in for one more at 9w, and I didn't get to watch it until the end to see the baby but it was super quick. ALL were only abdominal and they didn't seem to check around anywhere else or move it much. So I have no idea honestly!!! I was told this wasn't a viable pg in the beginning so I am a skeptic! LOL
So I guess I will check today and see if I manage to hear more than one again...and I think I will have a good idea before long because now is when the big growth spurts start and I will be HUGE by my 21w u/s if there are two in there! LOL I've been more sick with this one than ever. My head says, "you had 3 u/s...that would be crazy!"
Dh felt kicks from the outside yesterday. Neato!
