Are you ready for that magic moment? The meeting of the sperm and egg usually takes place between weeks 2 and 3. Here’s how 23 + 23 = 1 new life.


Mom's Tip of the Week

Did you know...?

Your prenatal supplement could be missing an important nutrient for your baby's brain. When choosing a prenatal supplement, you may want to consider one that has docosahexaenoic acid (DHA). Not only is DHA good for you but it's important for your baby's brain and visual development. The omega-3 fatty acid DHA is found naturally in fatty fish, but since many fish are tricky during pregnancy due to mercury levels, getting DHA in a prenatal vitamin is a good call.

Being 3 Weeks Pregnant

What's Happening in There

  • The sperm and egg meet. Usually, during week 2 or 3 of pregnancy, the strongest sperm makes its way through the cervix (the opening of the uterus) and travels up the fallopian tubes to meet the egg. When the egg is fertilized by the sperm, conception has occurred.
  • Your baby is a single cell. The egg is called a zygote after it is fertilized. Although it is only a single cell, the zygote has all the DNA needed for life—23 chromosomes from the mother’s egg and 23 from the father’s sperm. These chromosomes help determine your baby’s sex; physical characteristics, like hair and eye color; and to some extent, personality.
  • The zygote begins to divide. As the zygote travels down the fallopian tube, it divides into many more cells, resulting in a big ball of cells called a blastocyst. The hard outside shell (which will become the placenta) nourishes and protects the inner shell (which will become the embryo). Your baby is moving closer to a recognizable physical form—and a home in your uterus.
  • You might be preparing for multiples. If your ovaries release more than one egg, there’s a chance you’ll carry more than one baby. You could have nonidentical twins, triplets, or more.

Your Baby’s Brain Development

Now is the critical time to shore up your nutrition, if you haven’t already. The healthful foods and prenatal supplement that you consume are the building blocks of your baby’s development in the next few weeks. Some nutrients that play an important role in your baby’s brain development: iron, zinc, iodine, copper, omega-3 fatty acids (DHA and EPA), selenium, vitamin A, choline, and folate. Experts recommend that pregnant and nursing women get at least 200 milligrams of DHA per day.
