Update: Still pregnant. BUT NOT AT HOME!
When I went for my tests today the ultrasound showed my amniotic fluid was low. I then had a minorly unpleasant exam after which the doctor determined my water had broken.
-Due to the amount of "old blood" discharge I've had, it is apparently possible to also be leaking amniotic fluid and not realize it.
So I have been readmitted to the hospital where I will now officially stay until the baby is born. The goal is to get to 34 weeks (I'll be 30 tomorrow) at which point the risk of infection from my water having broken outweighs the benefit of the baby not being born. So if I make it to 34 weeks, we will then have a baby. Looks like Littlest is likely to be born in March instead of May. In fact he will certainly be born in March, as long as he doesn't demand to be born in the next four days.
There you have it. Everyone please send me staying pregnant vibes.
