might be pregnant?!

I started taking the pill on my first period day and started with the placebo pills 😬 I finished the pills and took three active pills for the next 3 days. On the 4th day, I had unprotected sex with my boyfriend and the days after. We haven't had sex in 20 days (long distance relationship). I got my period regurlaly and it only lasted 1.5 days of heavy bleeding and 2-3 spotting. Last week I felt really sick and threw up as soon as I got home from work and today I feel the same again. Really bad headaches and nauciousness; also, I had a little spotting as per today when I woke up and that's about it. I know that placebo pills don't protect from sex right away and I was sadly not aware of that. I will get a test tomorrow morning as soon as I wake up but as per today, I need answers girls!!!!!Â
