Ron&Jen0527:I began taking B6 for nausea after my first appointment and take it still. I'm kind of afraid to stop!!! My nausea was so horrible. I have been without nausea completely for only about 3 weeks. I still get it from time to time so I just keep taking it. If you want to quit, I'd wait a few more weeks. I've heard of some women having nausea up to 17 weeks.
My mom was sick the morning my sister was born. My friend had m/s well into the third-tri and DH's size 2 aunt only gained 6 pounds with each of her 10 pound babies because she was so sick for her entire pregnancy! I'm still doing the B6/Unisom, and am scared to stop!
