Period question

Tatyana • Hey I'm Tatyana . Wife and mom to 2 kids.
So the first day of my periods are usually really heavy and painful, my period started today and I have a bit of cramps and a very light flow, I'm wondering does that have anything to do with me having my 2nd baby and making my periods different and irregular, I was 13 days late on this period to start with. I'm not breastfeeding either so I don't think that has anything to do with it. Anyway could it be because of me giving birth or with age and hormones? I'm 24 by the way Thank you in advance
