period twice in one month?

So I got my period this month on the 6th & right after I got off my period I had sex with my boyfriend that same day I forgot to take my birth control pill because I stayed up late with him & I forgot to take it. & this week on Saturday we had sex again & I forgot to take it because I stayed up late with him once again. Now it's the 29th & I got my period again is that normal?. I don't have any cramps or anything that's really weird because i usually get horrible cramps when I'm on the period but I'm just bleeding & it's not a lot
