Pregnant?

Hi everyone, on July 22nd I had sex with my boyfriend and the condom broke and he came a little bit in me. I was on birth control for 9 days when that happened, and I got the breakthrough bleeding that happens on placebo pills about a week ago. I’ve been feeling a bit sick throughout the time I started taking the placebo pills, like feeling I will throw up if I don’t eat, started gagging just by looking at dirty dishes, and really strange abdominal pains. I’m planning on taking a test next week, but I’m just scared. What do you guys think? And I take my birth control always on time, never been late.
