Pregnancy Calendar

Week 11

• your baby will be 50mm or two inches long by the end of the 9th week
• eyelids are formed and will close over eyes until around the 24th week
• baby's head is becoming more rounded and makes up half the length of your baby
• this is the beginning of the fetal period, meaning that the embryo has developed into a recognizable human being and all major systems have been formed
• fingernails and toenails start to grow

Week 12

• the ears are fully formed but are still lower than normal
• baby will be 61mm or just about 2½ inches long at the end of this week
• sex organs are noticeably male or female, but aren't fully formed yet, gender might be hard to distinguish by ultrasound at this point
• bones really start to develop around this time
• If you have a prenatal check up this week, you may be able to hear your baby's heart beat with a device called a doppler, but probably not with a regular stethoscope
• you may notice your clothes getting a little snug around the waist as the uterus rises above the pelvis

Week 13

• baby opens his mouth for the first time and may suck on a finger that gets too close
• little eyes move closer together and ears move higher up on the head, making your baby look more like he or she will at birth
• the neck continues to become more defined and straight
• your little one is growing and growing, this week it is 2.6 to 3.1 inches long and weighs around half an ounce
• you may be able to feel your uterus just above your pelvic bone as it expands to accomodate your baby, placenta, and amniotic fluid
• end of the first trimester!!

Week 14

• your baby is around 3 to 4 inches long this week and weighs around 1 to 1 and a half ounces
• little feet are half an inch long, with tiny toes that are becoming more separate as the webbing between them shrinks
• Boy or Girl? After the 12th (14th) week it is possible to determine your baby's sex via ultrasound, although it is not always foolproof, so you might want to wait on the pink paint:)
• Are you showing yet? Everyone is different, and you may show earlier if this is not your first pregnancy.
