Help.

So i’m on birth control, and have been for almost a year. It always makes my periods wack and off track so i’m kind of used to it by now. I had two periods last month, Im pretty sure. But I haven’t been tracking them like I should be. My boyfriend and I have unprotected sex pretty often, he always makes sure to pull out. I’m super sketched out and scared though because I feel like I haven’t had a period in forever. Any opinions? Anything will help. (I also take my pill everyday at the same time.)
