Possible Gallstones?

This will be TMI, so please read with caution! Also I’m aware that to get a proper diagnosis I’d have to see my doctor. Before I go to that extent, I’d like to get advice from others who may possibly be going or has gone through this as well. Thank you!

I’m currently 20 weeks pregnant and it seems like my bowel/digestive system has gone completely haywire.

For the past 4-5 weeks or so I’ve noticed that now it’s as if I can’t go at all. I’ve been drinking coffee to help induce bowel movements but when they happen it’s very little. I eat soo much so I feel like I should be passing bowel movements just as much but I sometimes don’t go for over a week! At that point I feel very backed up and soo gross.

Today I’ve gone to the extent of taking Miralax (a laxative). Typically I like to stay away from them because my stomach/digestive system is very sensitive and certain laxatives really hurt. But I’m so desperate to feel “clean” inside so I’m going to this extent.

Whenever after I eat, I get this sharp cramp in my right rib cage near where my gallbladder is, however, I’m not sure if it’s because my uterus is growing and pushing my organs up to my rib cage. But I feel like all this buildup is possibly now affecting my gallbladder and causing gallstones.

Has anyone gone through this? Is what I’m feeling actually due to gallstones? I’m not sure how to go about this. I do know that if this laxative doesn’t work I will be taking a trip to my doctor to see what I can do.

I apologize for how long this post is but I want to provide as much information I can. Any advice would be gratefully appreciated and I’d appreciate no negative comments as well. Thank you in advance!
