Sorry tmi =constpation

Ok ladies we all know that you get constipated while pregnant ok that’s ok ! Well my dr perscribed me something that’s liquid and it’s like a laxative but now I feel like it’s not working well , and I’m eating healthy and walking so shouldn’t that get the bowels moving ? If I’m doing all that and taking the med she gave me ?!!! And also I have gas during pregnancy, is it supposed to hurt or just feel uncomfortable when you have gas ? Oh and when you have Braxton Hicks is it supposed to make the top part of your stomach feel tight and hurt ?
