Hi, I had unprotected sex on 9th July and checked using preg test kit on 11th July which was showing mild line and was confused so for safer side took ipill on 11th July and again on next day checked using pregnancy test kit and the result was negative and was calm.Now I got my periods on 27th July but the discharge was less and not much cramps were there.Last month I had got my periods on 28 June .should I be worried ? Are these signs of spotting or it's normal after use of ipill called as light period or withdrawal bleeding?should I check again with the preg test kit? And on which day should I check it ?
