Thanks so much, mamas! I have no idea what to think of my "symptoms" at this point... But when I told DH how big I measured myself at last night, he finally got silly about the possibility, which is a LOT better than his comments about finding a bridge to jump off of!
For him, it actually means he's taking it more seriously!
So here's what I know... I absolutely know conception date (was charting various signs, though not temping). At 11wks had our first appt with our MW (2nd pgcy with her). At first palpation she said, "Well, that feels like a healthy 16wk uterus!" We couldn't find a heartbeat, though, either high or low, and she suggested maybe I had fibroids (never had before) that were causing it to feel bigger.
Two weeks later she came back to try again. Fundus was a couple of fingers below my navel at that point - this is 13wks. Still no hb, so we started thinking there's another anterior placenta.
Three weeks later (16wks) she comes again and we find a heartbeat! By this point I'm definitely feeling a baby HIGH - and she confirms that my fundus is at my navel level and baby is way up there. Baby seems to like to stay in that area, too. Heard the heartbeat and some big kicks, too, so we all feel better! Joked about the possibility of twins and she neither dismissed the idea nor said she thought we had two. We briefly discussed multiples issues but mostly talked about things not directly related to us.
Now, I'm 17.5wks and finally decided to try measuring. My fundus definitely above my navel now. I measured 3 times and got two measurements of 23cm and one of 25, so I'm going with the more conservative 23cm for now. Granted I may not be getting it perfectly, but still! I have no history with previous pregnancies of measuring large, and my boys were 7lb14oz and 7lb2oz!
As for symptoms the worst has been the complete and utter exhaustion. I've called my MW asking about anemia (never had) because I have had such horrible problems with the fatigue - and this was at 16wks, when I thought it should've been lightening up already.
I've been constantly hungry pretty much the whole time. I remember eating in the middle of the night with my others, but I haven't this time. Just ALL. THE. TIME. when I'm up. Though I haven't gained any weight - I started out "fluffy" to begin with, and I've lost weight early on with my others, as well. Plus, I was in an exercise class this time, too, which was great but certainly burned more calories than in my previous pregnancies.
I have not been as sick this time, but have been plenty nauseous. It's really surprised me that I haven't thrown up as much, as I was sick well into the 2nd tri with both of my boys.
As of 15-16 weeks I could easily palpate the baby up high, but now I'm having trouble as the shapes I'm feeling don't feel the same as what I was feeling. I need to double check how big the baby should be by now. For a while I knew baby was about 5-6in long and felt exactly that. Now I feel more in there but I can't tell if it's baby in a funny position, or what!
There are NO multiples in either family, so I'm guessing if we do have two they're more likely identical... but I have done very little research in the area, other than a basic curiousity over many years!
I'm going to schedule an u/s for 20 weeks - just 2.5 weeks away. Unless indicated, that's the earliest my mw recommends having one. Though somewhere I read a poster say that it's better to have one earlier if you suspect twins to look at the placentas?
Anyhow, I have trouble believing that it's REALLY two, but I also have trouble reconciling the size that's been consistently big. I guess I need to look into 3rd pregnancies more and see if there's any propensity to be THAT much bigger.
Thanks for your input, mamas!!
