Constpation

Hey mamas I need help I am 5 weeks pregnant and I’m severely constipated. I mean my poop isn’t difficult to come out it just take days for me to actually have a bowel movement. I’ve eaten apples, bananas, lots of greens, ginger tea, warm prune juice and it makes me poop but only a tiny bit. I’m also feeling very nauseous like all day nausea I’m assuming because I’m constipated. Idk do y’all have any tips that made you go and deal with nausea? I need to go to work but I’m feeling so uncomfortable.
