Hi everyone I just did my second IUI a week ago today. My first one took but my HCG level did go up like it is supposed to. But I had a question to put out there sence we are all going through similar things. So I have done some ready on the internet and there is so many different answers on what days you can have implantation. I wanted to ask all of you because we all are go through the dreaded 2 week wait. What days if you noticed were your implantation days??? I have read you can have it from day 3-6 or 6-8 and even 8-12. Thank you so much for the help!!!!
