2 periods in 1 month & now a week later

Timeline:

• February 19, took Plan B

• Feb. 27 - Mar. 4, got my period

• Mar. 14, took Plan (please no hate, I had to.)

• Mar. 25 - 31, got my period (only 3 weeks after last one ended)

• Apr. 8 (only a week after period ended), which is today, I have spotting which I’m guessing is another period.

Has this happened to anyone after taking Plan B? I know it can cause irregularities, but I feel like this is extreme. I know I shouldn’t take Plan B as much as I did & I don’t, I wouldn’t if it wasn’t needed. So please, no hate or judgment. I just want to know what’s going on. I got my period so I’m not pregnant, what’s the spotting? It’s both light red sometimes & brown.
