Unisom and B6 for morning sickness

Nomi

My doctor told me taking B6 with unisom can help my morning sickness. I’m only 7 weeks and 2 days and my morning sickness is horrible! I’m scared to take meds due to possible birth defects. I’ve taken it for 2 days and it really helped and then my aunt who is a nurse told me to not take it until my second trimester. Has anyone ever taken it your first trimester and everything been okay?
