Oh dear..your schedule at work sounds exhausting. Eating right, taking time for you and exercising are so critical and necessary, especially now. My doctor reminded me that it's called 'labor', because it will be some of the hardest work you'll ever do. Women who are in good physical shape and healthy generally have a better time during labor and delivery. Stretching will help and will be an easy way for you to ease into a regular routine. The suggestion of yoga is a good one. Be sure to do stretches on the floor, as well as standing and find a few to do with a partner. I bet that 'best guy' in the world will help you. Leg lifts are good, starting slowly, to strengthen abdominals. Strong stomach muscles help during labor and make recovery much easier. You'll find it much easier to retain your pre baby figure if you're in shape now. Don't worry about doing everything at once. 10 minutes in the morning and 10 minutes at night are much better than no exercise at all. Much better. You'll gradually have more energy, too. You can increase the time gradually. There are many exercises your pediatrician or nurse practitioner may recommend. Check baby magazines, other new moms, or the internet. It sounds as if you do a lot of walking at work, so I'd concentrate on the stretches and toning. I exercised until the day before each of my sons were born. My labor was short and I recovered very quickly with little weight gain. Maybe the exercise helped. Good luck and good health to you.
