I am freaking out!! Someone please help me understand what's going on!

OK. So my last period was Jan. 26th. It is now march 11. I have had 6 negative hot and thought i started two days ago bit it was only medium spotting. No actual flow, only when I wiped. There was not even a need for a pad or panty liner. It was bright red at first then turned to a lighter pink. Then yesterday there was nothing at all. Today I had very light spotting again. Light pink only when I wipe with no flow. My breasts are VERY sore, i have had headache every day for a week, nausea, bloating, fatigue. What should I do now? Last hpt was taken yesterday it was also negative. What do u all think is going on and has anyone else had this happen?
