Hello babyloveyou, what do you mean when you say your "trigger" is tonight? What is this "trigger".
I did IUI in my last cycle as well, but it wasn't successful.
The gynae scanned be and said the follicles are ready and we proceeded with the IUI procedure on the same day. However, after I went home, I used ovulation test kits and tested negative for ovulation over the next 3 days! I only tested positive on the 4th day. By this time, the sperm injected would have already died. Though the gynae told us to continue intercourse after IUI, which we did, I feel that the gynae should have timed the procedure so that the injection coincides with my ovulation period.
Did your gynae give you any injection to release the eggs before the IUI procedure?
