Can someone please talk to me ?? I need help

It's been a whole week since I had sex. We used a condom the whole time. he took it off once but put it back on and we went back at it. The only time he came was in my mouth at the very end and that was it. The sex didnt last long and Idk He told me I'm fine and u can't get pregnant from him cumming in your mouth. I'm thinking of any other way. I shouldnt be worried everyone has been just ever since then I have been so paranoid and I have been having like period cramps and gurgling stomach. Like isn't it too early to have "symptoms" anyway ?? It was my ovulation / fertile week and i just ended yesterday and everyone has been telling me I'm totally fine and it's normal to have cramps during that time period. I think I'm just freaking myself out. I know it was dumb but I just need some help. I'm supposed to start my period in 11 days and I'm just scared.
