I don't know what's going on?

My periods are coming in two days. I hope I am pregnant and praying to miss these periods. I am feeling a lot of gastric, and feeling really emotional. I mean I am smiling at one side and crying on other. I am having discharge like pee and cramps in my belly. My vagina felt hot and full of something like blood will blast any moment. I had a test that was positive three days ago and after positive I took other two more tests that came out negative. I am very depressed. I don't know what to do? 😢😭😭😭
