Levonorgestrel
"So I promised myself if this works, I have to write a review to put someone out of their worrying misery because believe me I WAS SCARED FOR 2 WEEKS STRAIGHT. So I had sex with my s/o on August 1st, with no condom or form of birth control (yes I know dumb but hey I'm human ya know) and he came in me, completely. On this day, my period tracker app said I was fertile so this was completely worst case scenario to me. I took the plan b 3 hours after the incident, but boy let me tell you! I was nauseous for the whole week! In my head I was like "yup, I'm done for. I'm pregnant."

Fast forward to August 17th, I got my period a day early and it is HEAVY and PAINFUL. Plan b works. RELAX PLEASE!"
