Period 2 weeks after period?

So two weeks ago I had my period it wasn’t normal to me, so I talked to my doctor and she said it was normal with the pills (hormones).

But it seemed she just didn’t listen to me right and I’m not paying $$$ just for one more consult with her... umm sorry for that went on a tangent!

Anyways so it lasted 4 days. It was light and brownish; I tell you bc I don’t think it dried that quick with a new pad ... also I went to the restroom and when I did #1 it was like that lightly.

Now I have it again 2 weeks after except lighter and still like dried blood

It painful with lots of cramps and a lil dizzy... also no energy. I did go myself a pregnancy test and it came out negative:( /:)!

I may add that I’m more of a heavy period, cramps, and 5 day period person, but prob it’s bc of my 1 yr postpartum ... I think!

My sister said it could be from a chemical ?pregnancy!!! Add to that before my 1 yr old I had a painful miscarriage!!!

Do y’all think it’s normal?

Note: I had a c-section and been on the pill ever since I was able to!
