I have done several rounds of clomid and have had cramping with all of the rounds. I was so convinced I was pregnant because I was cramping, had sore boobs (sorry if tmi) and was feeling quite ill/bloated. But, BFN BFN BFN....went to the doctor, nothing, bloodwork showed that I likely didn't even ovulate....and so I continued with the Clomid and BCP to get a period. I will say, I had an AWFUL next period. (Sorry if TMI but I had large clots and severe cramping with this AF).
So...not sure, maybe I was preggo and miscarried? I don't know...I do know that I Clomid has screwed me up royally...even had blurry vision. Because I "did not ovulate" according to my monthly bloodwork, and I was up to 150mg of Clomid for 10 days...my doc has referred me for IVF...so I am waiting for my initial consult for that. I am dropping the clomid treatment and starting on Soy Isoflavones this month.
Best of luck to you. Clomid does work for some people. I certainly wish it had worked for me.
