Will you get pregnant if the guy rubs his penis to your butt hole then tries to put it in but it didin't insert?

Unlikely, but... Pregnancy is always a possibility in a woman in her fertile years. Urine pregnancy tests are available at any drugstore, and are very accurate if done correctly, and done after a missed period or 3 weeks after when conception might have happened. A woman can also go to a primary care doctor or an ob-gyn doctor for testing. Changes in mucus, discharge, and cramps can occur without a pregnancy.
