I don’t know what to do...

I don’t know what to do. I’m 11 weeks now. Superrrr constipated. I don’t feel like I’ve been eating enough to this constipated. I’ve tried prunes, juice and laxatives. Nothing seems to help and my stomach hurts. When I finally do get to go it’s not enough to relieve my stomach. I’m also super hungry but afraid to eat because I’ve been so constipated. In the last two weeks I’ve lost 8 pounds. I’ve also been having lots of morning sickness. Does anyone have any tips?
