My last period was August 28th also. I have long cycles (about 33-35 days). It kind of depends on how long your cycle typically is. I know that I ovulated yesterday but if your cycles are shorter you could have been fertile around the 12th. Your age makes you more fertile also. It is a possibility that you could have conceived. When do you expect your next period? If you are pregnant, you could get a positive result from a HPT a few days before you expect your period. I hope it works out for the best for you!

Thank you so much for responding to my question! My cycles are usually pretty regular the same time every month I'm neveer late or early if anything its off by a day or 2 nothing too crazy. I'm very scared and I'm freaking out, I'm assuming my period should come around the same time this month as well. Thank you agin!!!

danielle0826- No problem. Keep us updated. I don't know what your situation is and you do not need to share if you do not want to. However, I got pregnant unexpectantly when I was 23 years old also. I was terrified and I was freaking out. But it was the best thing that ever happened to me. I was a single mom for the first 2 yrs of my sons life. Although, it was difficult at times. I always found a way through those difficult times. God will never put more than you can handle on you. Good luck to you!
