"me and my boyfriend always have safe sex, but this time the condom seemed to come off inside of me and we didn&#039;t notice until after he finished. i took aftera about 1 hour after it happened. it really works. my ovulation window was around that time and i was freaking out. my period comes every 30 days and i got it on time! (two weeks after taking the pill). i&#039;m on my third day of having my period and it is lighter than usual, but not to a big degree. the only symptoms i got from the pill were dizziness, nausea, and fatigue. this was my first time taking aftera and it was very effective. the sooner you take it, the better it works."
