"this pill works! don&#039;t read these reviews 24 hrs a day like i did. i was so scared and worried myself sick but it works. i was on birth control but didn&#039;t take it at the same times. (wasn&#039;t using as contraception, more to regulate periods). period ended june 22nd. incident on night june 24th, took pill june 25th, 5 hrs after incident. withdrawal bleeding july 1-8. regular period was supposed to come july 13, i got it one day early on the 12th. so basically two weeks of bleeding in a month. even after that, it was heavy but i was worried about implantation and all that. but i got my next period august 8th and it is two days early according to my birth control packet, but right on time if i counted 28 day cycle! this works. trust it!"
