Nausea

I’ve been on zofran and prescription B6/unisom since I started my pregnancy. I’m 16 weeks and still vomiting almost daily. The meds helped some but my OB said he wants me to stop them because I gained 2lbs in 1 month from week 8-12. This was after loosing weight. Now it’s been another month and I’ve only gained .5lbs. I started this pregnancy at 130lbs. He said “sometimes some people can loose a little weight” 🙄 I hate my OB but I don’t have many good options in this area. I just hope the nausea goes away sometime soon because this is not fun.
