I had sex on last day of my periods i.e. 5th day of cycle.. my cycle is usually more than 30 days long.. can i get pregnant from this intercourse?

Maybe: Young, fertile women who receive semen in their vaginas tend to get pregnant. That's a major purpose of having sex, according to nature... to make new humans. Sperm lives a few days inside a woman, so in this instance, cycles longer than 30 days are probably ovulating too late to get pregnant, but cycles shorter than 30 days might ovulate early enough to let the egg meet a long-lasting sperm.
