You finally reach the 30 week mark, and you are rapidly approaching to have your beautiful baby in your arms. There are still (more or less) 10 more weeks to go. But remember at week 37 your baby is considered Early-term, so if you go into labor after that, your baby will be just fine.

Normal Pregnancy symptoms at 30 weeks!!!

Swelling: Mild swelling is to be expected at this time, and will typically go down if you get some rest or put your feet up for a while. Sudden or severe swelling isn’t normal and could be a sign of a problem, let your doctor know right away.

Trouble sleeping: Maybe you can’t sleep because you’re getting nervous or anxious about delivery, or just because your belly getting in the way. Experiment with different strategies for getting some sleep, see what works for you and stick to it. The giant body pillows for pregnant women are awesome, consider one of those.

Heartburn and/or indigestion: As baby starts to crowd your digestive system, it might not work exactly as it did before, be mindful what you eat.

Shortness of breath: As your uterus keeps expanding, the compression against your lungs increases, causing you to feel short of breath. You might find this to be especially true if you’re 30 weeks pregnant with twins. Don’t push yourself too hard, and slow down if you feel yourself gasping for air.

You might be experiencing other symptoms such as  Bloating and gases, Constipation, Varicose veins, mild fatigue, stretch marks, Braxton Hicks contractions, vaginal discharge, general Pelvic and Abdominal aches and pains. All those symptoms are normal, all part of the process of growing a baby in your uterus. Try to rest as frequent as you can, stay hydrated, stick to a healthy diet, and give yourself a lot of love, and soon everything will be much better after you deliver.

Fetal development at 30 weeks.

At 30-weeks your baby’s brain is developing ridges and valleys that provide more space for nerves to grow. Those wrinkles allow for an increased amount of brain tissue, a necessary change as your baby prepares to develop and become smarts for life outside your womb.

Various brain sections such as memory and speech continue to develop and grow.

Your baby’s taste buds are well developed so they can respond to sweet and sour tastes by now.

Regarding the baby movements, they are actively moving and flexing the limbs.

The baby’s body at this time starts growing faster compared to the head.

Now that baby’s brain and new fat cells are regulating the body temperature, the lanugo which is that soft, downy hair covering your little human’s body is beginning to disappear.

Your baby’s bone marrow has completely taken over production of red blood cells (before, tissue groups and then the spleen took care of producing the blood cells). This is an important step for your baby because it means she’ll be better able to thrive on her own once she’s born.

What to know about doctor visits?

You’ll be keeping tabs on how often the baby’s moving and whether his or her movements are consistent from day to day.

Here’s how you do it: Pick a time of day and set a timer. See how long it takes to get to 10 fetal movements it should be less than two hours.

On the routine doctor visits, these parameters are still checked.

Your weight gain.
Blood pressure.
Fundal height.
Fetal presentation.
Heart rate with Doppler(of the baby)
Fetal movements.
Signs of preterm labor.

If you have an uncomplicated pregnancy, you probably won’t have a 30-weeks pregnant ultrasound.

Only If any Size discrepancies, fetal breech position and/or signs of preterm labor such as Contractions, Pelvic pressure, Backache, Cramping or bleeding are present, an Ultrasound will be ordered.

Normal ultrasound images of a 30-week baby are as follow.

This is also a good time to start getting informed about Cord blood banking. 

Cord blood is what remains in the umbilical cord and placenta following birth. It contains stem cells that can be used to treat some blood diseases and immune system disorders.

Cord blood banking is a safe and painless procedure and is performed just after baby is born (it takes only a few minutes).

You can donate to a public facility for free so the cells can be used by others in need, or you can store privately for an upfront fee and an annual storage cost so it’s available only to your family.

If you do choose to bank cord blood, you should talk to your practitioner about it now so the necessary prep work can be done.
