First PP period?

I’m a ftm. My periods before pregnancy were 32 day cycles with 3-4 days of bleeding. It starts heavy then worked its way down. So I’m breastfeeding idk if that has nothing to do with it. But I’ve been spotting & medium period for two weeks. It seems like it’s going away for a day or two so I put a pantry liner next thing you know I have to put a tampon in. I’m just confused why have I been bleeding for two weeks? Is this normal?
