This might sound like a basic question but i genuinely dont know and im too shy to ask my doctor. we werent careful during my period days and now im a little worried. is it actually possible?
Chances are low during periods but not zero, specially if you have short cycles. Sperm can survive a few days so ovulation timing matters. So yes it is possible, just less likely.
Honestly its not a safe assumption that periods means no pregnancy. With irregular or short cycles ovulation can come early. If you want to avoid, better use protection na.
