The baby begins to breathe in the womb!  You may be able to feel your uterus this week.

Your Baby

The baby’s neck is growing longer and the space between the chin and the chest has increased.  The placenta is providing all of  your baby’s nutrition at this point.  The baby begins to practice breathing in and out.

The baby will grow to approximately 2.9 inches this week.

Changes in your Body

Congratulations, you have now entered the second trimester!  This period of pregnancy is sometimes referred to as the “honeymoon” period, as your early pregnancy discomfort eases and your baby is not big enough to cause the discomforts that may be experienced during the later stages of pregnancy.

You may be able to feel your uterus about four inches below your navel.

Girl or Boy....mmmm.
written by Happy Mama, January 31, 2010
Hey Ashley, I'm a first time mama myself and according to the old wives tales, I should be having a boy so time will tell. Looking forward to my first U/S Thurs. but won't really know til 2nd U/S at the end of March. Supposedly: carrying low is a boy; shiney hair and healthy long nails is a boy 'cause the girls take more nutrients from u and will dry ur hair and make ur nails brittle.
Excited

actually carrying high is a boy:] im hoping for a girl but not showing yet. im almost 12 weeks and have a u/s on wed. i had my first when i was almost 8 weeks so all i saw was a little blob which was still very exciting but i must say im way more excited to see that he/she looks a little more human now !:]

Carrying high doesn't really mean anything. It's another old wives tale

So sorry to hear that, Paula! He's a dirtbag for cheating on his pg wife!

written by PaulaGl, February 01, 2011
Thanks, Leonna. I know he's sorry, but I don't want him back. He'll be a good dad, but not a good hubby.
