I took my birth control for a month and a half and stopped, and about three weeks later i started it again. Then i stopped again after about a week. I thought it would make me start seeing as in i started right after i stopped taking them the first time. Am I not starting because my body wasn't used to the pills or could I be preg. I haven't had sexual intercourse but i have been close to him when he came. I am not sure if this is my pills or if i am preg. i am very nervous so please help.
