Vena cava

So tonight I went to the hospital for a scare of fluid leaking at 19 weeks. I’m a high risk so I freaked( everything is great baby looked good. Turns out I just peed and didn’t know it lol)

BUT in the middle of my ultrasound they laid me completely FLAT and within a few minutes I started dripping sweat, shaking, feeling like I’m going to pass out and throw up. It was a horrible feeling I felt like I was losing my mind.. it felt like the “whoosh” you get when you get an Iv contrast. I even lost my hearing. Turns out my baby was laying on my vena cava and my BP dropped down to 90/50 and they had to give me fluids. IT WAS SO SCARY!!!!
