I just recentally started using a generic birth control pill the day after my period four days ago. While having sex our condom broke and I am one hundred percent sure I got all of the semen inside of me. In order to prevent pregnancy I feel like I should use a emergency contricption. Is this healthy? Will there be any serious side effects? And most importantly how can I be sure it works before my next period? Thanks for the awnsers can not afford to see a obgyn at the moment.
