Ideas and Inspiration

Some pregnancy tests are sensitive enough to be used today -- if you get a negative result but think you are pregnant, wait another 2 to 3 days. Remember that first morning urine has the strongest concentration of hCG, the hormone pregnancy tests look for.

According to the March of Dimes, "In most cases, scientists do not know what makes a baby's heart develop abnormally. Both genetic and environmental factors appear to play roles. Among the few environmental factors known to contribute to congenital heart defects are a virus and certain drugs.

Women who contract rubella (German measles) during the first three months of pregnancy have a high risk of having a baby with a heart defect.

Certain meds also increase the risk. These include the acne medication Accutane, lithium (used to treat certain forms of mental illness), and possibly certain anti-seizure medications. Drinking alcohol in pregnancy also can increase the risk of heart defects -- babies with fetal alcohol syndrome (FAS) often have them. Recent studies also suggest that use of cocaine in pregnancy increases the risk of these birth defects.


Understanding due dates

Confused about "age since conception," LMP and due dates?

We know it can be a little mystifying -- you practically need a calculator to figure out your due date, conception date and LMP date. One common question is, "How is my due date calculated" -- and another biggie: "What's the difference between gestational age and menstrual age."

LMP and menstrual age

Week one -- when we're talking about the typical 40 weeks of pregnancy -- starts on the first day of your period. Yes, it's true that you're not actually pregnant yet, but most caregivers count everything from this day, anyhow. The number of weeks passed, based on the 40 week term from your last menstrual period (also known as your "LMP" date), is called menstrual age.

Gestational age

Two weeks later, when -- and if -- one of your eggs is fertilized, gestational age begins to mark time from baby's conception. This term lasts about 38 weeks, which is the amount of time your baby is actually developing.

Keep in mind: Any due date is only an estimate -- and only about 5% of babies actually arrive on the date they're "due," with most babies arriving anywhere from 37 weeks to 42 weeks. Your caregiver will typically assign your due date based upon a 28-day cycle.
