This is TMI

I got my period last night.

Today I got up had a shower and put a super tampon in.

Half an hour later I've bleed through.

When I pulled it out the blood was a different color than it normally is...

It was sort of a dark plum color. Browner than usual but not like it had dried a little.

It was sort of a discharge texture.

When I put the next tampon in it hurt and felt like something was in the way of me pushing it half way up.

Should I be worried??

Sorry about the grafic details..
