Week 7: How your life's changing

You're in the throes of the first trimester, when many women suffer from common pregnancy woes. Keeping food down may be next to impossible, thanks to morning (noon, and night) sickness, caused in part by the pregnancy hormones coursing through your body. Stash a box of crackers next to your bed, and eat a few to curb the nausea before getting up. You may also need to use the bathroom a lot more often than usual — your blood volume increases dramatically when you get pregnant, which leads to a lot of extra fluid getting processed through your kidneys and ending up in your bladder. The nausea should fade as your pregnancy continues, though you may continue to make frequent trips to the bathroom.
