I had a blastocyst transfer on Sunday. I didn't place too much weight on the fact that I got sore boobs following that, as I thought it might just be the hormones in the pessaries you have to use. But now my boobs just aren't feeling sore any more, and I am getting worried that my embryos have disappeared. I can't do my pregnancy test for 4 more days. Anyone got a (reassuring?) similar tale?
