Hi I'm in college and me and my boyfriend always use protecting. I decided to get birth control pills for the first time. My last cycle which was nov 17th, that's when I started the birth control. I took the pill for 2 weeks then I stopped for the side effects was weird to me. Now my cycle is going on 7 days late. I took a test and it was negative. My symptoms all show that's it's coming but it's not here. Cramps, sore & tender breast. Backaches. My cycle never been this late before could it be cause of the birth control? Or in the worse case Pregnancy? I know I'm stressing because of it buts creeping me out. Can someone give me some answers please
