More natural constipation remedies?

So I’m about 8 weeks pregnant and so far I’m going like 4-5 days without pooping every week to the point of just being nauseous and miserable and my stomach gets huge. At the end of the week I cave in and take a gentle laxative but the day I have to take it the cramps I get all night and into the morning are straight up insane and so painful and I don’t even take a full dose. I can’t do this the entire time. Besides more water what are some more natural ways I can keep things moving so I’m not so miserable😩
