the worst part of my pregnancy

I just need to vent somewhere that ill sound less crazy. and no I'm not airing out my relationship, because honestly, my relationship is very good. the worst part of this pregnancy is it makes me paranoid. I swear. ive never thought my fiance has cheated or would it is or anything. until I got pregnant. I'm sure its because my last serious relationship I got cheated on so many times. so many. so sometimes I get paranoid anyways. but i hate feeling this way brcause i know it's stupid of me, but I cant help it. I was wondering if while pregnant anyone elses hormones just made them think kinda crazy? its very frustrating to me.
