dizzy feeling

Lovemylife • Mom to two awesome girls. 1 MC. Had my rainbow baby boy 6/5/2017!!!! So in love 😍
I am 16 weeks and 2 days and I feel totally off. Like dizziness in my head or pressure. Anyone have this before? I thought I was just hungry so I ate and drank orange juice but that didn't help. I don't want to call Ob if it is nothing bc I feel like I call all the time n they r getting annoyed. Anyone deal with this? Any advice?
