Is it okay to have sex the week of my period?

“I’ve been taking the pill for 2 years now.Is it ok for me to have sex the week of my period? Is there any chance of me getting pregnant, without using a condom?”

A: “If you have been taking your pill correctly, everyday and at about the same time everyday it is 99% effective at preventing a pregnancy. However, if you frequently miss or forget to take your pill the effectiveness decreases. Therefore, if you are consistent about taking your pill you are protected from an unintended pregnancy. The birth control pill does not protect against sexually transmitted infections.”
