I am newly married and had proper sex with my wife of about 3 times and will she get pregnant of this 3 sex? Please help me out

She could. It really doesn't matter how many times. She could have even gotten pregnant the first time. Unless you guys are usig birth control. No because I 100% effective but if you guys are using because then its pretty unlikely that she would be pregnant.

Depends on her cycle and when she ovulates. It only takes one time, whether protected or not.

If you had sex within a few days of her ovulation, its possible. At maximum, healthy couples are fertile for 6 days during her cycle.

Sperm *can* live for up to 5 days in fertile quality cervical fluid. Once an egg is released it is viable for 12 - 24 hours = 6 days between the two of you.

I recommend seeing a doctor for information or doing some research on your own to get more specific information.
