I masturbated in my washroom and I dom't clearly remember if I had washed my hands or not. Then I touched many things (like cupboard, bottle, door, polythene packet) then after 10 minutes, I met my girlfriend and I fingered her. I did not finger her directly, I rubbed her panties. I did not insert my finger in her vagina, I had just rubbed the upper part of her vagina from outside of her panties. Now, her periods are late by almost 3 weeks. Though she has very irregular periods (like they don't come for 2 months) and she is taking medication for it. I'm scared if she is
pregnant. Please help.
