Story of the twins: This January I found out that NuvaRing does NOT work. At 8 weeks, I had an ultrasound at my first doctor's, and the baby looked healthy but they only saw one. The next couple of appointments my blood pressure was mysteriously elevated, so for my 18 week u/s they sent me to a high-risk specialist. He set the u/s on my belly and immediately said "Oh there's two heartbeats." I thought he was kidding, so I said "yeah you're funny" and Dr S. said "here I'll get them on the same screen." So it turned out there were two babies... Twin B immediately flashed the camera and Dr S said "whoa, he's a boy!" When we tried to get a look at Twin A, it flipped its butt to the camera, all the while Twin B was trying to get back onscreen (apparently he is a spotlight-hog). So the elevated blood pressure was explained (it's common for twins) and I had to switch doctors and stay with the high-risk specialist. At 18 weeks we knew Baby B was a boy. At 24 weeks we saw a perinatologist and she confirmed that Baby A was also a boy. They were in separate sacs, but the amniotic membrane was very thin which made the peri believe they were identical, but she couldn't get a good look at the placenta because Baby B was in the way.
