I am 25 years old i don't have my period regularly I see it 2 or 3 times a year but right after i have my period i have unprotected sex is it possible for to get pregnant or not?

Yes, it is still possible to get pregnant even if you have irregular periods and only menstruate a few times a year. Ovulation can occur at unpredictable times, and sperm can survive in the body for several days. If you have unprotected sex after your period, there is a chance that you could conceive, especially if you ovulate shortly thereafter. It's essential to consult with a healthcare provider for personalized advice on contraception and menstrual health.
