Idk if this is dumb or not

I’m on birth control (implant) and have been since half way through May and only recently have started having foreplay and sex with the guy I like and by I mean sex it only happened last night but we’ve fooled around in the past (like where he could have maybe got his cum on me)

And my stomach has gotten really crampy and bloated imscared that I’m pregnant even though it’s pretty much 99% unlikely I’m just really paranoid and have been for awhile help???

Anything I can do to keep my mind off of it 🙃

Sorry if this doesn’t make sense
