I just wanna poop!

I'm 9w3d and I've been having trouble pooping for a week now!! I'm also having upper abdominal pain. I took miralax for 3 days and I think it helped a little. I was too scared to take it any longer?  Anyone else have this issue? This sucksssss. I wish I could be one of those glowing and happy pregnant ladies. I just feel like dog shit 100% of the time. I have to FORCE myself to be nice. 😑😑😑😑😑
