Alright so I had sex for the first time on December 22 and like twice after that the next day and like a week later. A little bit after that i was spotting and I didn't know why. Now I am supposed to start my period but instead I am just spotting. I also have tender breasts, cramps, mood swings, etc. I just brushed those off as normal pms symptoms. We used a condom every time and I am on birth control but this is basically the first month I've been on it.
