I think I'm pregnant and we just broke up..

I can take a test on the 8th.. but I just have a really strong feeling that I'm pregnant. Never felt like this before. He broke up with me today, he knows pregnancy is always a possibility since we don't use protection but he doesn't know I feel like this, I didn't want to say anything until I knew for sure. I'm so heartbroken and I don't know what to do..
