Period changes HELP

Lucia

Soooo I had a baby on March of 2017 and my period completely changed after having him I now get horrible cramps witch I never used to get I can’t even use tampons in the beginning of my period because it gives me even bigger cramps I get super super emotional like I can go from zero to 100 real quick and I get soooo blotted witch also didn’t use to happened .. So I’m just wondering has this ever happened to anyone else is this normal or should I be worried ? O and for reference I got induced I was in labor for 36 hours I pushed for about an hour and a half and then I had to get emergency c-section because my baby got stuck
