13 weeks pregnant

You are now 13 weeks pregnant (or in your 14th week if that's how you prefer to count it).

The fetus is now nearly 3 inches / 7 to 8 centimetres long from crown to rump and weighs nearly an ounce / 23 grams -- about half a banana. Its unique fingerprints are already in place. And when you poke your stomach gently and she feels it, your baby will start rooting -- that is, act as if she's searching for a nipple.

If you're having a girl, she now has approximately 2 million eggs in her ovaries; she will have only a million by the time she's born. She'll have fewer eggs as she gets older, and by age 17, the number will have dropped to 200,000.

As for you, the fog may be lifting, so to speak. For many women, the side effects of early pregnancy -- frequent urination, intense fatigue, nausea -- diminish sometime in the second trimester. Your uterus, while large enough to announce to onlookers that you're indeed pregnant, isn't so huge that it gets in your way. Even though birth is months away, your breasts may already start making colostrum, the fluid that will feed your baby for the first few days before your milk comes in.

You're officially in your second trimester, the fourth to sixth months of pregnancy. That's great news for two reasons. One, your risk of miscarriage has dropped dramatically, and two, many women see early pregnancy symptoms, such as morning sickness, subside - you may notice a distinct improvement in your libido as the nausea recedes and your energy levels rise.
