I came off my period the day before I had sex without a condom, he cummed in and on me. I took the morning after pill for the first time exactly 24 hours after, they said if I'm five days late on my next period to go back I'm on my fourth day and still no sign. I've been having strange stomach ache feels like I'm going to have diarrhoea and feeling bloated alot as well as painful headaches and always feeling tired. what is wrong with me?
