Sex using withdrawal method

“my partner and i having sex together 4x this month only…we use only withdrawal and i know that withdrawal is not effective…my problem until now i didnt have period its already 3rd week and thats my menstrual day. i took one pill only but not the day of contact and i stop it bec my partner says that its only for contact to take pills…if there’s possibility for me to get pregnant?”

A: Withdrawal is not an effective method of birth control. I do not understand what kind of pills you are referring to. For birth control pills to be effective, they must be taken everyday at the same time, regardless if someone has sexual contact that day or not. If you are not using a reliable method of birth control, there is a potential for pregnancy.
