PLEASE HELP AND GIVE ADVICE?!?!?!?!?!?!?!?!?!?!

I know I have posted about this a lot… But I am just scared and I can't really talk to anyone about it. Seven days ago I had sex. We used a condom and he came in my mouth at the end and he took it off and I remember him putting it back on. I'm just trying to remember every little detail and I have a terrible memory so it's kind of freaking me out… He's telling me I'm fine my friends are telling me I'm fine but ever since that night. I have been having slight cramps and gassy stomach/gurgling. I don't know if that's one of the earliest symptoms of pregnancy or if you can even get signs this early. but I don't really know what to do. I was ovulating that week so it scares me even more that it's like a higher chance of pregnancy. He told me he did not cum in me. And I know that's right at the very end he came in my mouth and we were done. I just cant stop thinking about it. It's been a week and I have stressed myself out to the max and every time my stomach hurts just the slightest I think the worst. My period is supposed to come in 11 days and Im soo scared I know stressing can delay it but even if I miss a day I will flip. If I take a test now will it work ?? Is it too early ?? Am I just freaking myself out ??
