Can you get pregnsnt on your petiod?

Yes, but low chance: If your cycle is perfect then you should not get pregnant during your flow, but few women have perfect cycles. At times, people may have "light period" for some reason, thinking it is safe, but that may just be break-througk bleeding and ovulation is occuring, thus chance of pregnancy. Best practice is prevention..Be cautious! good luck.

Very unlikely: If you are bleeding the lining of your uterus is shedding. Even if you did ovulate there would not be good mucus to allow passage of sperm or an adequate endometrial lining to support a pregnancy. Even so - there is always the exception. There have been women who have conceived on every day of their cycle.
