I have been on the pill for 2 years and take it every night around the same time. We use condoms every time as well. 2 weeks ago we didn't use condoms and instead he pulled out. I for the last week have been having mild period cramps but i am not due for my period for another 3 active pills and 4 placebo. I am that worried I can not sleep or eat, am I overreacting? Is the pill effective enough on its own?
