Pregnancy - First Trimester

I am very tired. I seem to go home everyday from work and take a nap. Before knowing that I was pregnant, I would try to hide my tiredness from Brian because I was ashamed that I wasn't able to survive on the 7 hours of sleep that I was getting at night (which is also more than usual). Now that we know that I am pregnant, I let myself sleep as much as needed. Brian was complaining for a while, but then his best friend Tyson explained to him that this is a symptom of pregnancy and he needs to let me rest without hassling me. Now Brian encourages me to sleep.
