I got my periods on the 15th of August and I had sex on the 26th of August... and once again on the 10th of September I had sex... my periods are about to start on the 13th... so are there any chances that I can get pregnant... can I get pregnant.

Yes. One week before your period is the most ideal time to get pregnant. I would take a test.

Any time you have sex pregnancy is possible, even during your period. So yes, it's possible that you're pregnant.

Wait until your period is late, at least a week, and take a pregnancy test using first morning urine. If it's negative wait another week or two, or until your next period is due, and test again, or see a doctor for a more accurate blood test.

Yes very possible, as to the percentage or "odds" no one knows that even doing it exactly on specific times is not 100 percent.

But yes you could be pregnant, now you have to wait and see if you miss your next period ornot

Do you know your body, when you ovulate? You could most def. Be pregnant. Wait until missed period.
