The worstttttt!!!!! TMI, constipation/gas pains/horrible bloating

Ok ladies, someone please talk to me about constipation relief/gas pain relief/bloating relief. I am literally dying and hurt so bad. I am 14 weeks 2 days. I have tried absolutely everything I’ve been told to try like benafiber, stool softeners, drinking an insane amount of water, increasing fiber is an absolute no no (it makes the gas/bloating worse), probiotics, exercise, and I take magnesium daily. I am also allergic to dairy so I can’t have yogurt. Does anyone have ANYTHING else I can try!?!?
