Change your Daily Routine

Even everyday tasks like scrubbing the bathroom or cleaning up after pets can become risky when you're pregnant. Exposure to toxic chemicals, lifting heavy objects, or coming in contact with bacteria can harm you and your baby. Here are some things to (hooray!) take off your to-do-list:
- Heavy lifting
- Climbing on step stools or ladders
- Changing kitty litter (to avoid toxoplasmosis, a disease caused by a parasite which cats can carry)
- Using harsh chemicals
- Standing for long periods of time, especially near a hot stove
Also, wear gloves if you're working in the yard where cats may have been, and wash your hands thoroughly after handling raw meat.

Check Your Medications
Check with your doctor or midwife before taking any over-the-counter medications, supplements, or "natural" remedies. Even non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen should be avoided—studies suggest they increase the risk of miscarriage and damage to fatal blood vessels.

Track Your Weight Gain
We know—you're eating for two. But packing on too many extra pounds may make them hard to lose later. At the same time, not gaining enough weight can put the baby at risk for a low-weight birth, a major cause of developmental problems. Recently the Institute of Medicine (IOM) issued new guidelines for weight gain during pregnancy. Here's what the IOM recommends, based on a woman's BMI (body mass index) before becoming pregnant with one baby:
- Underweight: Gain 28-40 pounds
- Normal weight: Gain 25-35 pounds
- Overweight: Gain 15-25 pounds
- Obese: Gain 11-20 pounds
Check in with your doctor frequently to make sure you're gaining at a healthy rate.

Rethink Your Spa Style
Pregnancy is definitely a time for pampering, but you need to be careful. Avoid saunas, which can make you overheated. Ditto for hot tubs: According to the American Pregnancy Association, it takes only 10 to 20 minutes of sitting in one for your body temperature to reach 102 degrees Fahrenheit—nearly the limit of what's considered safe for pregnant women. Also, certain essential oils can cause uterine contractions, especially during the first and second trimester, so check with your massage therapist to make sure only safe ones are being used. On the taboo list: juniper, rosemary, and clary sage. The same goes for over-the-counter medicines and supplements containing these herbal remedies; don't take them without first consulting your obstetrician or midwife.
