I've been on birth control for 3 years. I had sex with my boyfriend Sunday and when he pulled out to switch to a different position, he noticed once he pulled out the condom was no longer on him. So I stood up and the condom was way up in my vagina. I took my finger and slid it out and it wasn't broken or anything and flushed it. We didn't continue sex but I just want to know if I should take an emergency contraception? I've been kinda anxious since.
