My fiancee was on her periods and on her last day i inserted my penis in her vagina n had sex for only some seconds. Thereafter we continued further with condom. Can she still get pregnant even though it was her last day of period? It is said that having unprotected sex in periods is safe.
She has no infections, but i'm still worried if i can get one STD, if any. Is it so?

Pls throw some light here friends.
