I missed my pill the day after i had sex but did not realise i had until i went to take the next one. I have been feeling sick,more tired and i need to pee more often than usual, i am gettin cramps but my period is due so it may be that. I had also realised that sperm can live inside a person for a few day. I had done some research and found out that i had be ovulating around the time i had sex. After i missed the pill i continued to take it as normal. Could i be pregnant?
