I am in the same boat as the above answer....I took Clomid from Feb. 9 - 13 50mg and I ovulated later than I normally do.......I started getting mild cramping but nothing crazy and on March 2nd I had light pink then brown spotting..I thought it was old blood from my period getting ready to start.....My period was due March 8th, I did a home preg. test March 9th, and got my BFP.......so its possible you are preg.....but also possible that the cramping was late ovulation cramps....
