I need reassurance

Carson
Okay so I had sex on the last day of myfertile  window this cycle, with a condom and he didn't finish. my period ended two days ago. it was a totally normal period.
but I've had weird stomach aches/cramps since it ended- which has never happened before.
I just need someone to tell me that I'm not pregnant bc I know I'm not I'm just freaking out bc these cramps are not normal.
