Hello! I’m a 19 year old woman and have been having unprotected sex. Used plan b three times within the last three weeks (ik im horrible) because my birth control prescription expired and was in the process of renewing but started my birth control and I’m just nervous whether or not I’d be pregnant because the more often you use plan b the less effective it becomes right? had a three day period right after too. What’s the possibility of me being pregnant? when should I check if I am?
