I am now in my third trimester (29 weeks & 5 days pregnant) And ever since then I started to feel sick. Yesterday I went to work and I had to leave early because I was getting lightheaded and I was about to faint. Today I ate breakfast with homemade orange juice and when I got to work I was feeling really sick again, I was getting lightheaded again. I been drinking a lot of water and it never seem to help. I never got morning sickness or anything like this when I found out I was pregnant but now that I am in my third trimester I feel like crap.
