So I have been having unprotected sex and weeks after maybe 3 weeks I have been having these weird cramps . They hurt badly and stomach pains . They don’t hurt to the point I can’t handle it but they definitely are uncomfortable kind of like a period cramp but a little bit more intense I didn’t know whether it was an ovulation cramp or what being that this app said I have one more day of ovulation left .. but I never had cramps like this during ovulation so could I be pregnant ? Btw I took some tests maybe like two weeks ago or a week ago and it was negative but the nurse said it wad too early to be taking one .. what do you guys think
