Is this normal?

My last period was January 31 to February 4 and then I got it back again February 15-18 which never happens, it skipped March probably due to stress and then I got it back april 13, and I am still on it. it was 25 days late.

My period was heavy for the first two days and then medium and yesterday I thought it ended but I had one light leak and today as well it keeps getting lighter and only soaked through a liner and it’s the fifth day, is this normal? My periods are usually 4 days
