Tmi tummy trouble

Has anyone dealt with constipation, vomiting, and reflux combo. I'm only 7 weeks, but I feel like I'm being poisoned. I've tried earring things with fiber, juice, stool softner. I feel like I swollowed acid cement. Got so dehydrate I needed an iv and take Zofran everyday. Pills make my stomach so uncomfortable and crampy. Help plz?
