If you have your period and play with yourself brother is playing u like playfighting on his puberty can get pregnant?

No, you cannot get pregnant from playing with yourself or from your brother playing with you, even if you have your period. Pregnancy can only occur if sperm from a male ejaculates into the vagina of a female during intercourse or other sexual activity. Playing with yourself or having your brother play with you does not involve the exchange of sperm, so there is no risk of pregnancy. Additionally, puberty does not affect the ability to get pregnant. A person can only get pregnant if they have reached reproductive maturity and are ovulating, which typically occurs after puberty.
