Pregnant?

Jordan
Okay so me and my bf had sex about 3 weeks ago, while having sex our condom broke lucky we heard it and stopped. He hadn't came yet but had a lot of precum. Today I'm feeling very sleepy, my boobs hurt, and I have a headache, could I be pregnant? I am not late on my period, but I start in 6 days. I am super paranoid i could be pregnant though.
