In the past 3 weeks, I've lost over 10 lbs dealing with nausea. My doc prescribed Zofran which I took as needed for 3 days. Yesterday, 7 weeks on the dot, I woke up with no nausea at all. Still gassy and bloated, but no nausea. Today I wake up and it's the same. Should I call my doc? I have been having some back and hip pain but it doesn't seem to be "cramping" as much as "soreness." I'm a nervous nelly as it is, this is totally freaking me out! Suggestions? Advice? Help!
