My doctor gave me Sprintec birth control while I was a virgin. She told me to take it to see of my body could adapt to it. But I wasn't having sex, so I thought there was no need for it. I lost my virginity on Sept 12th, he didn't go all the way in and he didn't ejaculate. I felt the symptoms such as cramping joints and when I would pee it would hurt. So I took the pill Sept 15th, which is 4 days before my period. Did I do the right thing?
