Hello, I am 20 years old. I had sex for the first time in two months with a new boyfriend and about a day or two later I started spotting. We had sex again a couple days ago, and I am still spotting. I am not due to have my period for another week and two days, I am on birth control. We used protection, if that matters. And also, he was the biggest I have been with and it was kind of rough. I think that may be why but I would just like another's opinion.

Odds are it was due to the sex. Fairly common to have some spotting now and then in the day or two afterwards. Maybe try a different position, ease off a bit on the roughness, and make sure you are well lubricated to ease some of the friction and potential irritation.
