Early Pregnancy

I am very early into my first pregnancy (almost 5 weeks, yes so so early i know), but I am never one to keep secrets or anything. I feel like I’m falling asleep at work. I’m a physical therapist and I basically talk for a living, so it’s super hard to hide my intense fatigue. I know it’s normal to feel this amount of fatigue this early, with building the placenta and all, but man oh man it’s hard to not have someone to complain to! I of course have my husband, but I want someone at work. I told my best friend about the pregnancy, but she’s so far from being at this stage of life that it doesn’t feel like she gets it. How do you guys get through the first trimester when you can’t talk to anyone about it? I’m feeling very isolated.
