Did you stop taking the pill at the end of your pack, or in the middle?
The bleeding on August 29th is considered to be your period, even though you had one on the 13th. When you stop the pill mid-pack and have withdrawl bleeding, it is considered your period and you should count 4 weeks from that day to determine when you're due for your next period. From my calendar you're due on September 26th +/-.
You might be fertile right now. Be sure to BD, and take a hpt if you don't get a period on the 26th.
Good luck!!
Thank you so much for the info. I am going to the docter tomorrow for my annual and I will take a perganacy test then just to be sure. Wish me luck
