So confused

So I had my period at the end of Feb. Between the 26th-1st of Mar. Then I had spotting or another period, (it was light but red) so maybe my period just stopped for several days?) and that was the 5th-7th. The following week I started having nausea/vomiting, fatigue, headaches, the works. And that's never happened before. Now a week later, starting the night of the 18th, I got severe cramping, like really hard cramps. And then on the 19th I started bleeding, it's bright to dark red/brown, depending on the concentration of it on my panty liner. And this was light for me like a panty liner a day not very much. And it's continued through the 20th and this morning. Both the blood and cramps.
