I'm 17 days late. I did have unprotected sex and he did ejaculate in me but it was like the 17th day in my cycle and I know girls ovulate the 14th day of their cycle so I didn't think anything would happen it didn't happen before. I havent took a test yet cuz I'm scared but the only signs of pregnancy are my boobs are sore i was sooo tired last week I get really moody now which is unusual for me and I been getting on and off cramps in my stomach which i didn't get before. Could I be pregnant?
