The Growth Progress When You Are 13 Weeks Pregnant

  • Fingerprint

Little fingerprint are starting to form on those cute fingers. Their final pattern will be set by the time you reach mid-pregnancy. Now as he has start to discover how to suck his little thumb, he might be busy practicing his new skills.

  • Intestines

Loop of intestine, which connect you and your baby through umbilical cord has now moved to their abdomen. Your baby is beginning to swallow amniotic fluid.

The fluid is mostly water, but it also includes protein, carbohydrates, fats, and enzymes. Any remaining fluid is turned into urine by his kidneys, which he will pass back into the amniotic fluid.

  • (Yeay!) Baby’s Gender

You can start having your ultrasound scanning to know your baby’s gender. If your baby is a boy, his testicles have now formed, and his penis is growing. If you are expecting a baby girl, her ovaries are developing and already contain about 2 million eggs.

Things to do When You Are 13 Weeks Pregnant

  • Healthy Meals

It will never be too late to start eating healthy meals. As it is more important for you to take healthy food from now onward as your baby needs more energy for their development.

Focus on whole foods that contain lots of vitamins, minerals, and good fats. Whole-grain toast with peanut butter is a solid way to start the day.

Fruits high in antioxidants, like berries, make wonderful snacks. Try incorporating lean protein from beans, eggs, and oily fish into your meals.

Avoid eating seafood with high mercury such as mackerel and tuna. You should also avoid eating raw or undercooked foods. Not only that, intake of caffeine and alcohol should also be avoided for certain period.

  • Light Exercises

Light exercises are recommended with doctor’s permission. You can take a walk, swimming, jogging, yoga, and light weights are all great options.

Also, you should start finding alternatives to abdominal exercises when you are 13 weeks pregnant. You can try sit-ups, which require you to lie flat on your back. The increasing weight from your uterus can decrease blood flow to your heart, making you lightheaded, and in turn, slowing the delivery of oxygen to your baby.

  • Testing for earlier Medical Conditions

You may have an ultrasound to evaluate nuchal translucency. The scan can check whether there is additional fluid under the skin behind the baby’s neck.

This is important in testing for some medical conditions that may affect your baby, such as Down syndrome. Blood tests are also used to screen for Down syndrome, Trisomy 18, spina bifida, and other problems.

Week 13 Symptoms

1) Energy Restoring

(Finally!) As your placenta is taking over, you should feel like you’ve got a bit more of a spring in your step. Plan out how to use this energy correctly. Add some exercises in your bucket but not until hurting or burdening yourself.

2) Risen Sex-drive

Entering second trimester will give you some relieve of dizziness and vomiting. As your energy is getting boosted, your sex drive is also boosting up. But make sure to check with your doctor first, especially if you ever had a miscarriage before. 

3) Discharge

Do not panic over the vaginal discharge, as it is a normal symptoms when you are 13 weeks pregnant. It is known as leukorrhea, which is thin, milky, and mild-smelling discharge cause by the production of oestrogen. It protects the birth canal from getting infection. Make sure to wear a thin panty liner around this time to avoid your underwear from getting messed up.

4) Veins Appearance

You might not like them, but these are super important during pregnancy and are a sign of the increased blood supply to your growing baby.

5) Heartburn and Constipation

Both are a common thing that will accompany you through the end of your pregnancy. The muscle at the top of the stomach relaxes which allows digestive acid to rise and cause that familiar burning in the chest.

Stay away from spicy or fatty foods to avoid heartburn.  Add some high-fibre snacks into your diet, such as fruit, vegetables, and whole grains for your constipation.
