So my boss and I were walking to a meeting at another building few blocks away from the office and I almost passed out.
I kind of felt weird when I got up from my desk, and as we were going down in the elevator. Then when we walked out of the building. I felt very light headed, dizzy and weak when we got to the site. I walked into the building told my boss I felt like I was going to pass out and I needed to lean on the wall for a second. My boss (the only one who knows I am pregnant) was very worried and ran and got me a chair and made another employee who worked in that site sit with me when he went to get me something sweet. I drank some water and took a few deep breaths and I started immediately feeling better. Then he came back with cookies and orange juice and made me sit for a few minutes.
I am completely fine other than being mortified.
