REPOST :Is there a possibility I could be pregnant? Please READ?

My lmp was 5-24. My af always arrive like clockwork or a few days before. For the past 3-5 days my have been so sore they burn!!! And still they're sore!!! I have to pee a lot even when I don't drink much liquids?! I have taken 3 tests so far and all were negative. I have a 26-30 day cycle. Anyone have a period 5-24 and found out they're pregnant?
