Very heavy & cloth first PP period

So gross I know. But. Exactly 6 weeks after giving birth I started what I assume is my first post partum period. Day 1 it was picking up like a normal period. By that night it was HEAVY. I mean every hour having to change pad and underwear heavy. And every time I went to the bathroom I was dropping clots. It’s continued that way for two more days. And the clots are large.

I haven’t been to my Pp checkup because of Covid. I was anemic from my c-section and am taking iron daily. But I’m worried about the sheer amount of blood and size of clots. At what point should I honestly be worried? Should I call my OBGYN? I’m not close enough to go in. I’m several hours away at the moment.

Anyone else had this happen?

This is my second baby. First one was all natural. No issues with healing. My first PP period was lighter than normal. And it was more than 6 weeks after though I don’t remember exactly how long.
