Normal?

This is the first month without clomid. I did 3 rounds and decided to stop until we get my hubby tested. I have pcos but ive always had regular periods, just longer cycles. I'm normally not a spotter either. So 7 days before my period, I have some spotting. Just pink tinged mucus. It only lasted for a few hours and only when I wiped. Yesterday, I was supposed to start my period. I was spotting the same way again with cramping. Still no period today. I took a test 2 days before my period was due to start and it was negative. So has anyone else experienced this with stopping Clomid?
