Pp period?! Wtf

I had an emergency c section and now I’m 5 months pp. I’ve only gotten 2 periods in that time. Before having a baby my flow was so light and short I wouldn’t need to use tampons all the time and i never got period pains. Now my flow is sooo heavy and long. I can’t go 2 hours without my tampon filling and blood pouring down my legs. I thought I was bleeding to death the first time I got my period and called my doctor crying lol. And my cramps feel like my contractions did but constant. Wtf is this normal does it continue or will my cycle go back to how it was before I had my baby.
