pregnancy scare

my boyfriend and I had sex a few days before my ovulation week, but the condom broke. I would've taken plan b but I can't really afford it. we did the water test on the condom, and it wasn't like a waterfall, it just dropped when you touched it. and then during my ovulation week, I didn't get my usually egg white disharge. the texture was like creamy but dry at the same time, and now, I see a dry brown discharge and I'm really scared. please help
