WTF IS HAPPENING !!!

Is it possible to get pregnant during your cycle or when it’s actually suppose to come on ? Because tbh i believe as long as my cycle not on I’m going to have sex..my fiancé is honestly trying to get me pregnant and I’m not ready for that (He’s 40 I’m 24) he came in me several times the days my cycle was suppose to come on and now it’s late..BUT THESE CRAMPS ARE THE DEVIL HIMSELF LIKE AT THIS POINT I WANNA TAKE MY ENTIRE UTERUS OUT AND SEW UP MY VAGINA !!! My last pregnancy i had a full cycle the entire first and second trimester. could this really be a thing ? Did he push my cycle back a couple of days or did he shoot the club up & copped a few victims ? HELP!!!!
