Any advice?

Hello! my first time posting, I am 22 years old. I was on birth control for about 6 years.. i got off in april and have had some irregular periods, missed a month.. last month I had spotting but then it was actually a period.. this time i’m roughly 6-9 days late.. mild cramps, 2 negative pregnancy tests, very sleepy just wanna eat and sleep, spotted one day and also had some yellow mucus ( no odor )... headaches, sometimes seeing spots like a migraine, period coming or pregnant, I need help!!

thank you!
