13 mm gestational sac. Spot that looks “suspicious” of a yolk sac. Too small to see a fetal pole or a heartbeat. Could be normal, yes, in theory. My RE was clearly trying very hard to be encouraging and optimistic, saying that it looks “on track.” But (goddamn doctor google) it seems that 13 mm is the very top end of the range in which you can see the gestational sac and not yet a yolk sac and it still be a viable pregnancy. So I’m one measly millimeter and a semantic debate over the word suspicious away from a blighted ovum. Not too comforting. Could I ever just be in the safe range? Ever? I’ve seen SO MANY reports from women who see strong heartbeats at six weeks. Last time it measured 5w6d (really wish I knew what the gestational sac measured in mm) and had a slow heartbeat. Feels doomed. Now I feel like every twinge that I had been taking as reassuring is really just a cramp foretelling the end, and that it’s only the progesterone supplementation that’s holding off bleeding. I’d been doing REALLY well about not obsessing over checking for spotting so far, but methinks the next eight days are going to be different. I truly just about had myself convinced that it was only terrible timing that killed off all the others. That I just needed the Clo.mid to ovulate at the right time to get the progesterone production to a sufficient level. Signs don’t seem to point to that yet. But maybe just maybe I can still squeak by and be one of the ones who’s tortured week by week yet gets to week eight or nine before everything somehow suddenly looks perfect after all. Maybe. Maybe not. Maybe.
