Should I call my doctor?

Ha
I'm 39 weeks and 4 days and I've been super nauseous all day. I just got in the shower and about half way through I started to feel sick. I started to get light headed so I put the water on nice and cold and stood under that for a little hoping it would help. I had to jump out and sit on the toilet because I thought I was gonna faint. The original water wasn't even too hot. I've had it way hotter recently. I don't know if this is normal seeing as I'm a FTM.
