Help!! Passing out

Tiffany

Currently 24 weeks pregnant. Over the past few weeks I’ve had several episodes of almost passing out / blacking out. I get cold sweats, loss of hearing, tingling in my fingers. I can’t even go from sitting to standing without feeling like I’m going to fall over. I don’t have a glucose test done till 28 weeks. Should I make an Appointment to be seen by my doctor?
