Tried to have sex for my first time but it wouldnt go in at all. he didnt cum. happened 2days after period ended. chance of being pregnant?

Yes,but too unlikely: An ejaculation plus a nearby egg are usually needed to create a baby... and ejaculations can happen easily. Thus, a woman having unprotected sexual activities of any kind should be ready for a pregnancy and a cute new baby. That means she and her husband should get everything else in life ready for a rare surprise baby in the home. Meanwhile, use reliable contraception if not wanting a baby yet.
