Pregnancy or Period symptoms with Clomid

So I took my 2nd round of clomid 50 mg this month. I noticed a day or so after ovulation I had very light spotting for 1 day only. My AF is due today according to my chart. Yesterday I had cramps and spotting. Thought AF was coming cause I kept feeling wet. I had sex last night and there was spotting again with brown, dark red with CM. Ok I said my cycle is here this morning. So far there is nuthin on the pad. Also I usually get sore breast a couple of days before my AF. I noticed this morning I have sore breast on the day of my expected period.

Has this happen to any of you ladies on Clomid and you were pregnant or AF came?
