So i am on birth control and i just started fitness and we have to go swimming in two weeks and i cannot use tampons and i am suppose to be on my period the week we go swimming. So could i just skip my pills for a week like when i dont swim so i start my period early. Once im done my period could i just take the pills i skipped. Im not on birthcontrol because im sexually active i just take them for acne and to regulate periods.
