Irregular periods??? Someone help!

Hailey

So, I need suggestions on what’s going on with my body. Usually my period are veryyyy regular. Well in the middle of March, I had a 7 day period. That is normal for me. However, at the end of March I had a 3 day bleed. In the middle of April I had another 7 day period. I got off on the 20th and now I’m literally bleeding again. What could be going on??
