Stomach issues

So I'm 6 weeks pregnant and having some major stomach/digestive issues. I have yet to have morning sickness (knock on wood-it will probably start tomorrow now 🙄) but BMs have been miserable. Every 2-3 hours I get awful cramps and thr urge to go to the restroom. I'll try to go for the longest time and nothing. Sometimes I have a BM sometimes I don't. If I do then I have relieved afterwards until the next episode. The cramping is very uncomfortable. I tried miralax this morning so I'm hoping it's working it magic and tomorrow will be better. I eat fruit and veggies everyday. Along with lots of water. How else can I find relief?
