My period started on August 10th and lasted a week. On the last day I had unprotected sex on (August 16), he didn't finish inside me but i decided to take Next Choice as soon as possible. The following morning bright and early i bought it and followed the directions. One week later on August 23 i started bleeding and it lasted for about 3 days, it was like how my usual period (same flow) but shorter. Now i'm wondering if that was a good sign, that the pills are working? And my next period should i expect it counting after the bleeding i had on the 23rd or from the 16th? I'm trying not to stress out but i really want to have my period so i'll know if i'm going to be okay.
