probably tmi but I really need advice

I am 14 weeks post partum. My baby is strictly bottle fed. At 6 weeks I went on seasoniqe birth control (which I was on before conceiving and it worked great). SO I bled and spotted for almost 12 weeks post partum and it finally stopped, but I continued to loose a lot of thick discharge. then a week later I start to get pretty noticeable cramping and slightly brown mucus discharge again which is still happening with an occasional spotting. I know it's not uncommon to spot while on birth control, but is this normal? Starting to think my vagina may never be the same hahaha. There is very little chance I could be pregnant, though this is what I experienced last time. Is anyone else experiencing anything like this??
