Levonorgestrel
" I took levonorgestrel under the brand Postinor 2  after an incident with my boyfriend. My boyfriend's semen got over my vaginal area and some of it did get inside me (shallow penetration) and this was during my ovulation period. Took the first pill in 43h, second pill 12h later (postinor requires you to eat 2 pills 12h apart). 1 week after taking the pills I had a lot of vaginal discharge and tender breasts which really scared me because they resembled early pregnancy symptoms, but exactly 2 weeks later, I got my period. It was on time and flow was as per normal."
