Thought I was going to pass out at the gym!

I'm 25w3d. My belly ligaments were feeling sore so I took a week off from the gym. I had a feeling today might be a little rough, and it was. Everything felt harder; weights felt heavier, my heart was racing more than usual & my belly ligaments were complaining. I figured it was from the break or because baby shifted & feels heavier since I last worked out. I started feeling really hot & as if I was only breathing in hot air, so I went by an open window to breathe.

When I did dumbbell flys (something usually easy for me) I suddenly felt not good... and I recognized what kind of "not good" it was. It's that thing where my blood pressure will suddenly drop to 80/40 & I'll feel like I'm going to pass out. It happens a few times a year to me. It comes on quickly, first I'll feel like I'm in a sauna & can't breathe, then dread or nausea, and then I'll start seeing black clouds paired with dizziness. That's usually when I call out for my bf & I'll lay down in wherever spot I am before I fall down.

I think the hotness & breathing was my first sign but I mistook it for just being at the gym. I got the feeling of "dread" that comes right before the clouds or nausea so I knew right away, sat for a bit & then came home 😓 This seems to be the first time I was able to stop it before it goes through the whole course (one time I totally blacked out & when I woke up my bf was trying to pick me up off the floor). Now I'm laying down & still not feeling too great.
