Hi we've just had our first ivf cycle & i've got a couple of questions, i'm not sure when my period date should be my 1st day of my last period was 15th Aug and my cycle is 26 days but i'm not sure if the same applies once i've had ivf. I had two embryos transfered on 4th sept so i am 1 wk in with 1 wk to go til i test & i'm on a knife edge, nipples are painful like weights hanging off of them. One embryo was 6 cells and 1 was 7 cells is this good ? Would love a reply to help me get through this.
