Clomid

Hi! I miscarried this August and recently spoke with my dr and started a round of Clomid 50mg for 5 days. It's been 7 days since my last dosage and I keep getting cramps in the pelvic area, lower right side, but my AF is not suppose to start until feb 4th and according to all my apps I won't be at peak ovulation until the 21st. Does anyone else have any experience with this medication.
