Dizziness+poor circulation+suddenly sweating

M

The past two days I’ve had a few “episodes” off suddenly feeling like I’m going to faint (so dizzy, vision is a bit off), all the suddenly overheat and get so sweaty, and I’ve also noticed my legs, feet and arms falling asleep very frequently.

I have been outside and it’s been hot out when this has happened. (I have been chugging back the water though)

Is this anything to be concerned about or am I just a typical preggo lady in 35 degree weather.
