I am 21 and my gf is 20 .3 days back we cuddled and there was precum on my penis .i think I touched it before I started fingering here .can it cause pregnancy? She is supposed to get her periods around 15th feb. Today she had a thick creamy vaginal discharge .i read precum contains some sperm from previous ejaculation but I masturbated 3 days before that incident even urinated before I fingered her. Can she still get pregnant?
