I can't believe the baby is 30 weeks. It went by so fast. Well, and slow in the meantime. I got to enjoy one month without nausea and fatigue. Worked 80 hours a week but felt ok. Now into the third trimester fatigue is coming back. I am so sleepy all day. My work doesn't help either. Have to do night calls every three days. I also get short of breath when walking and climbing stairs. Legs feel like they have climbed a mountain. It's amazing how a little person change so much on our body! Human physiology!
