Can i get pregnant if i have unprotected sex during my periods?

No, but...: No, but life can surprise you. If one is having her regular normal period at the expected time, then she won't get pregnant during the first few days of her period because ovulation is much later. If she has sex near the end of a long long period, and she happens to ovulate early that cycle, and is carrying some rugged sperm that were able to survive a few days... The unexpected might happen.

No: Period is by far the safest time of the cycle to have sex.
