Hi, I did IVF to have my first child. I was very lucky, and it worked first go. During the two week wait I had all of my usual symptoms when AF (period) is coming, even period pain. I was more bloated than usual, but I put that down to the fact that they had just been messing with my ovaries, taking out eggs. Anyway, there was really no way of knowing until two weeks after the transfer, I did a HPT the night before I went in for my blood test, and it came back a faint positive. Even after the positive home test and blood test, I still got period pain, and even a bit of spotting, but it turned out to be fine. Nine months later along came my healthy little baby boy. I know it's really really stressful. Hang in there. I hope you're as lucky as me.
