Well last week ago I was on top of my boyfriend & we were doing dry humping & dry sex. I only had my underwear on & he had his shorts & boxer on & I was wondering if there is any chance I could be pregnant like that? & I'm getting worried about it & stressed about it. This few days I start noticing some white stuff in my underwear, sometimes my underwear be wet & yellowish . I haven't had my period yet & I'm getting very worried about it
