Hey ladies! Can anyone tell me if this is normal?

I got my first post partum period Jan 1st (happy new year to me! 😬), and experienced period cramps for the first time but figured it was normal. They werent horrible but I was a little uncomfortable.

Prior to being pregnant, I had a heavy flow but I had never experienced period cramps.

Now, I am on my second post partum period and the cramps, my god, its horrible. I feel like Im in labour. I have cramps that knock me over and I can hardly breath through them. Between cramps, my lower abdomin hurts. Im also bloated and gassy. I am bleeding quite a bit (filled up 3 menestrual cups today). I took a pregnancy test just in case and it was negative so thats not it.

I am going to call my doctor tomorrow if its not better but like, is this normal? I have no odea what period cramps are like
