I am either 8 or 9 dpo, I had THREE days of positive OPK's which I've never had. Unless one maybe was dark but not pos?

Anyways, this is my first cycle on Clomid after over a year with 2 chemical pregnancies and a miscarriage. I have had symptoms the entire time taking the pills and afterwards. Headaches, cramps, fatigue, sore breasts, hot flashes, everything! But now, the cramps are more painful and vary from my uterus/below belly button area to my ovaries, and my breast tenderness is more of a shooting pain on the sides.

Did anyone else's symptoms last their whole cycle? Or could this be early pregnancy symptoms? I feel like it's probably too early though.
