Aftera
"I had unprotected sex with my partner on my ovulation day and he pulled out before ejucalation but I was scared of pre-cum so I took Aftera 12 hours later. The side effects are  crazy. I had VERY BAD mood swings and painful cramps for almost a week. Lost my appetite completely. Then suddenly all the side effects went away and got my period today (3 days earlier than the expected date). I took plan B before but the side effects were not as bad as this one ! 
My partner did not finish inside me so I'm not sure how effective Aftera is. 
Please please never have unprotected sex. The side effects of these pills are crazy and waiting for your period to come is brutal."
