I just wanted to post what symptoms I experienced, I know it can be helpful for some. I had an IUI (intrauterine insemination) on Nov. 7 and 8th, felt cramping on left side on the 9th. Early morning on my 4dpIUI I got really sick throwing up and stuff, not sure if that was anything related, maybe something I ate. On my 5 and 6dpIUI I felt some mild cramping and on my 7dpIUI I had major diarrhea. The next day (8dpIUI) I felt like I was coming down with something, I felt a bit feverish and just had no energy. I never really got sick, after that day I felt fine until 11dpiui.
My nipples were a little sore, which I thought was weird because my breast usually starting hurting about a week before af is due. On 12dpIUi I was cramping really bad but thought it would be too early for af. Later in the day I realized I was spotting and thought af was definitely on her way. Devasted, I lost all hope and just waited for af. The next day came and nothing, no more spotting just had weird yellowish /bronwish cm and my nipples still hurt which was unusual for me. I realized that just maybe the spotting was due to implantation so I tested and there was a very faint line. I called my doctor and had b/w done, she comfirmed. I still have to get b/w done just to make sure that the HCG levels are getting higher and so for so good. I hope this helps, I know it can be very stressful not knowing and any glimmer of hope can be helpful. Baby dust to all!!!
