Hi. Me and my gf were rubbing genitals over our cloths and there were three layers. I ejaculated. Her lower was wet too. Then i rubbed her genital with my hand. Then she cleaned everything and changed her cloths. I suddenly thought about pregnancy. And i am worried that she would get pregnant. Its been less than 2 hours to this. And this happened at the date of her upcoming periods bt she didnt get period they were already late but after doing this its been one day she still dont get .Is it the condition to get worry or not?
