Me and my boyfriend had sex for the first time ever (we were both virgins) on feb 20 i was supposed to start my period on march 1st it is now march 5th and I still haven't had it. I've had a lot of gas though and a lot of mood swings. Normally before my period starts I get breast tenderness but I have not had that. We used a condom and I was so paranoid that that night I got the condom out of the trash and checked it for holes I didn't see any but I'm still super worried can someone please help!
