So me and my girlfriend recently started having sex. A few times we did it without condoms but I didnt finish in her.

She recently got off birth control and hasn't gotten her period yet but lately she's been having cramps etc etc and we're not sure if it's either from her being off birth control, her period coming, or if she's pregnant.

While we have sex (with condoms) we notice a thick white fluid coming from her vagina, I'm 99% sure it's not me because I pull out when I finish even with a condom and it's not as stretchy as semen.

If it means anything she's 2-3 weeks off birth control, about 1-2 weeks since our first unprotected sexual encounter. She took a pregnancy test yesterday and it was negative.
