You do not have to act gingerly or anything. As long as you are not riding horses or skiing where the risk of falling at a high impact on your belly is greater your body does a great job of protecting the growing baby. That is what it is made to do nurish and protect. When you get to be in your third trimester bending will get to be very hard as you will have to bend around the baby. Both my kids hated it when I bent over. If I was sitting at a table or desk and bent over to write or eat they would kick me. As for food sandwich meat, sushi(the kind with raw fish), soft unpasturized cheeses, and alchol are the only ones I can think of that you really have to stay away from. Watch what you are taking for medications whether it be herbal, prescribtion, or OTC. Talk with your doctor on what they feel is safe. Make sure you are taking a prenatal with Folic Acid. I had trouble swallowing them so my midwives told me I could take flinstones and just take two. Both my kids can out fine. You should make sure to see a doctor soon they usually like to see you around 8 weeks, good luck!
