Fully clothed dry humping and Mutual masturbation with girlfriend approximately one month ago. On birth control. Fully clothed. Worried about pre-*** transfer... Girlfriend touching me, touched abdomen, she got up and washed hands. Worried that pre-*** left on abdomen was touched by my hand and then rubbed in through her underwear. No skin contact with vulva (touched underwear only). She was wet.

She has been complaining of headaches, nausea, fatigue, dizziness, blurred vision. Sore breasts 2 weeks ago. Headaches, and fatigue for 2 weeks, dizziness is more recent. Comes and goes now. Still tired though. However, she has been unusually stressed as well, and may have recently switched brand of birth control pills.

What is the likelihood of pregnancy here. I realize theoretically it is possible, but what do you think?

What else could these symptoms mean!?
