Welcome Molros, I'm not sure about the pain you were feeling. I get all sorts of weird feelings around there and just can't figure out what half of it is. It may have been implantation pain?
11 blasties, what a great haul! I hope this next one sticks for you. The two week wait is awful isn't it? Good luck for your BT.
I had my second ultrasound this morning which seemed fine, a couple of follicles were around 17mm. Not sure when I will trigger yet. I've got my internet cheap POAS ready and waiting. Is it too early to test yet?
Good luck everyone.
