Feel like TMI: I feel like I’m constantly full of poop!

I’m 7 weeks with my third child. I haven’t experienced this feeling before. I feel like I’m really backed up and have a lot of poop to get out (I know tmi!) but I am going a couple times a day and it is always solid, regular BMs. My stomach feels uncomfortably full like I am constipated.. wondering if anyone has experienced this? I feel like it’s contributing to my morning sickness. I tried an enema thinking maybe I’m just really backed up even though I’m going regularly but that didn’t seem to make that much difference.
