Then yesterday morning, we went from spotting to bleeding. It was a qualitatively different event. I freaked out a lot and called my doctor, who then scheduled an ultrasound for yesterday afternoon.
There is no bad news. The good news is that the babies have grown (though not as much as I'd like) and their heartrates are perfect. They also found a subchorionic bleed next to baby B. It was very small, but could explain why there was bleeding. I wish it wasn't there and I can't understand why I have a clot when I'm on lovenox and baby aspirin. It makes me more cautious than ever about going off the lovenox any time soon.
So now I'm on "pelvic rest." I'm not supposed to lift anything heavy or to stand while I'm at work. I contacted the CA clinic who said that 70% of their IVF patients have some bleeding in early pg (very much like the link above suggests). In addition, the "vast majority" go on to deliver healthy babies. They, however, hinted that they would have recommended full bedrest.
I do think everything is going to be ok. The babies look great. I really think it's going to turn out ok. It just wasn't a lot of fun yesterday.
