I got my periods on 30th June. My bf and I had unprotected sex on the 5th July. But I took an ipill within 9 hours after the intercourse. On the 14th, I had slight bleeding rather spotting which continued for 2-3 days. As per the due date, I experienced some bleeding on the 27th July. But the bleeding is very less as compared to my regular periods. Is that a normal period?
