First postpartum period

I had my first postpartum period last month at 2 months pp, it was super light I could have worn the same tampon all day (I didn’t of course but that’s how light it was). This month I started my period a couple days ago and the first day was pretty light but the last 2 days have been extremely heavy. Having to change my super tampon every other hour if not sooner and wearing a pad as well for extra protection. I’m getting clots almost every time I wipe as well. Just wondering if this is normal. This is my third baby but my older ones are 6 and 8 so it’s kinda hard to remember some things. It’s also the first time I didn’t go on birth control after delivery. After a bad experience with depo we decided no birth control this time and we are wanting to try for our last one soon as well! Sorry if it’s TMI but I’m just wondering if I should worry or if this is normal? Thanks!
