How soon can pregnancy symptoms start? The bf and I had sex 1 day after my fertility cycle and my boobs arent hurting but my nipples are extremely sensitive, i constantly have to pee. Also ive wanted nothing but McDonald's fries for the last two days (hate their food). I need some advice ladies! Anything will help. My period isnt suposed to start for another 5 days. And i get random weezy feelings during the day.
