your symptoms and changes during the 10th week of pregnancy.

Your Baby

By pregnancy week 10 your baby is growing big enough to weigh in! Your baby may be more than an inch and a half long, or roughly the size of a kiwi!

Changes in Your Growing Baby

Your baby is growing tremendously by the time you reach 10 weeks pregnant. As your pregnancy continues you'll notice periods of time where your baby goes through rapid developmental changes. Your baby starts being referred to as a fetus rather than an embryo. During the fetal period our baby is less at risk for certain birth defects and congenital malformations, so give yourself a pat on the back for a job well done!

Your baby has reached an important developmental milestone. While it is still important that you avoid any potential toxins throughout your pregnancy, you can rest a little easier knowing your baby has past the most critical stage where congenital malformations are most likely.
Keep in mind that exposure to common toxins included second hand smoke is still very harmful during pregnancy. If at all possible avoid environments that may expose you and your baby to harmful substances during pregnancy and especially at 10 weeks pregnant (like second hand smoke). Don't hesitate to express our needs if you find yourself in a precarious position. Most people will bend over backwards to accommodate the needs of a pregnant woman.

Now your baby's organ systems are developing fully. Tissues are forming in the kidney, liver, heart and intestines. Within the next three weeks these organ systems will undergo amazing developments. Your baby will also start growing details, like fuzzy hair and toenails! By the end of this week your baby will also start swallowing and may even start kicking (though you won't be feeling those precious first kicks yet!).

Your Body's Development

Your body is undergoing many developments, though you still may not be showing much at this point in your pregnancy. By now you are probably feeling more fat than pregnant, but remember you are pregnant and you have a baby growing inside of you! Revel in that little tummy for now and your little secret. In a few weeks you'll be hard pressed to hide that precious tummy.

Changes in Your Body

Now is a good time to start taking photographs of your belly. Many women like to keep a photographic record of their belly that shows the changes in their belly from week to week. Years later you can look back and show your little one how much your tummy grew each week.

You may have heard your baby's heartbeat for the first time at your doctors office. Many fist time moms describe the sound of their baby's heartbeat as similar to galloping horses. Don't fret however if you haven't heard this yet, in a few weeks most women will have heard their baby's heartbeat for the first time.

If your partner hasn't accompanied you to your prenatal visits yet consider inviting him in the future. This will help your partner get acquainted with your doctor, the birthing process and help him bond with you and the baby during your pregnancy. While your partner may not admit it most enjoy being helpful and participating even in run of the mill office visits during your pregnancy. Your partner will also have the opportunity to address any questions or concerns he has about the pregnancy or about being a father with your doctor.

First Trimester Miscarriage

Losing a baby is a sad experience for couples. Unfortunately, you are not out of the woods for a first trimester miscarriage. Roughly 80 to 90 percent of all miscarriages (which is defined as a pregnancy loss in the first 20 weeks of gestation) occur in the first 13 weeks of pregnancy.
In most situations, you did nothing to cause the miscarriage. Roughly 50 to 70 percent of first trimester miscarriages are caused by chromosomal abnormalities in the fertilized egg. Sometimes, an early miscarriage occurs after the fertilized egg doesn't properly implant into the lining of your uterus. A majority of women who suffer from a single miscarriage will never understand the exact cause of their pregnancy loss. It's only after you have two or three consecutive miscarriages that a doctor will do a full-scale workup and evaluation to determine the potential cause.

If you are living a healthy lifestyle and you have no symptoms of a threatened miscarriage (like vaginal bleeding, abdominal cramping, low back pain), your baby is probably fine. Try not to worry about miscarriage. Contact your doctor if you're stressed about anything. He or she should be able to alleviate your fears and anxiety.
