Ladies, I'm in the dreadful 2 ww and obviously cannot wait to test! I've been analyzing everything and pretty much driving myself nuts. I had my IUI only 13 hours after the HcG trigger shot (was on Gonal f for 8 days before that). My gyno did an ultrasound right before the IUI (around 6pm) and my follicles measured 23mm and 26mm and my endo lining was about 11 and she said that I'd ovulate the following day but that she didn't want to wait until the next day because it could have been too late. My DH's numbers were great but now I'm worried that it was too early. I've heard that even though washed sperm can survive up to 72 hours, it can swim beyond the fallopian tubes and can lose potency. Then, 4 dpiui I had 2 small drops of blood and was wondering if it was implantation bleeding (but probably too little to be it) or effect of progesterone. Any one with a similar story? Successful IUI? Please help!
