suffering from HG. Reglan pump thoughts

Currently 13 weeks and have been suffering from HG. Three ER visits for meds and fluids. I've tried every medicine from Reglan, phendergan, diclegis, and now currently zofran. Still vomiting so much. Literally miserable. Dr said never step is a Reglan pump. Anyone have exerpience w this. Nervous about having a pump of continuous medicine but at this point anything to feel some what better. Have three little ones at home already and feel so bad that I can't play with them.
