I had sex on July 16 at 3:00 am and took plan b the next day at 1:30 am( it's been 2 days since I've had sex) , but the day after I had sex I I started my period and then took plan b, but my period has been lighter then usual. I have also been experiencing cramps, being bloated, and not really being hungry. I'm worried that I might be pregnant because he wasn't wearing a condom the whole time but when he ejaculated he was wearing a condom and pulled out before he ejaculated. So could I be pregnant or do those signs mean that plan B is working ? Or am I paranoid and shouldn't worry?
