Lately I've found that I can't stand up for too long, otherwise I start feeling like I'll faint. It's such an uncomfortable, bad feeling. Also sort of like my heart gets beating faster and I have to try to take deep breaths, and my skin feels funny. I remember having this same symptom when I was pregnant with my daughter, but it makes it no less kind of scary. Anyone else experience this? I'll be bringing it up with my doctor at my next appointment.
