Is it normal to bleed for 2 weeks?

Last period was in February. I was pretty regular and had my period every 3 1/2 weeks. Came always 1 day early, on time or 1 day late.

In March I never got a period.

It's April and aunt flo never left for 2 weeks. First was spotting & not bleeding a little more but not crazy heavy.

What's wrong with me? Lol!
