I made out with my girl friend after a year and shes still a virgin. The most i did was rub my penis in between her butt cheeks but disnt ejaculate but there must be precm. Her period is late by 5 days . Initially she got few cramps but today she had a small light brown dot . Due to eating habbits she has gained weight too prior to this and shes been doing yoga too. Whats happening ? Is she pregnant
