Pregnancy Week 15 – Weekly Development

Your 15th week of pregnancy is a continuation of the relief that you have been experiencing. By week 15, you’re about 3 and a half months pregnant.

With morning sickness all but gone and your body feeling renewed and energetic, you’re rearing to go again.

Now, there would be noticeable changes in your outward appearance. Your Breasts would be enlarging, same with your nipples and belly and you should seriously consider getting a new set of clothes. Weight gain is going to be on a whole different level, but you need to watch it.

Some weeks ago, your baby was as small as an apple seed and organ formation started at a point as well. Now, your baby is practically as large as an orange and moving around in the amniotic fluid.

Your baby is now roughly the size of an orange.

In a few weeks, you would start to feel your baby moving inside of you and with your body adjusting to mid-pregnancy, there may be changes in your emotions too. Anxiety, elation, basically a mix of different emotions, and as always, blame it on the hormones.

Your libido may see an increase or you might not feel up to it at all as your body is changing. You would need to talk things over with your partner so that he understands exactly what you’re feeling.

Your Baby’s Development

At week 15, your baby is about the size of an apple or orange, measuring around 5 inches and weighing around 3 ounces now. Although this size is still pretty small, a lot is going on within your uterus.

The skeleton which is going to give them their form is already developing and your baby is moving around a lot more now. With body parts constantly moving, you would start to feel the movement soon.

Your baby would begin to use their arms and legs to kick around and you may sense some fidgeting too. Grip continues to develop at this too and your baby would be able to suck its thin now.

Recall that last week, your baby was rehearsing various expressions and working on facial muscle. This week, your baby would be able to squint and grimace.

Your baby is still growing hair and skin, and eyebrows are continuing to form. It is also beginning to experience the concept of light and sound with bones in the ear developing rapidly.

Soon enough, your baby would be able to hear the sounds of your voice, heart, and your digestive system. Although your baby’s eyelids are shut, they would still sense and respond to light.

Your Body & Symptoms

At 15 weeks, some major transition is going on in your belly. Your uterus would still fit snugly within your pelvis during the first trimester, however, the second trimester is different.

As your first trimester drew to a close, your pelvis started to expand in order to fit the rapidly expanding uterus.

At a point, sometime around week 13, your uterus would begin to sit higher up in your belly due to insufficient space in the pelvis. This is when you begin to show.

The time for uterus ascension differs from one pregnant woman to another. At 15 weeks, you might still have a pretty flat tummy with only a slight bump while someone else could be very obvious already.

If it is a repeat pregnancy, you would show early on, but if this is your first, there is a tendency for it to take a while before showing. In addition to these, here are some other symptoms that you may notice at week 15:

1.   Gaining Weight

Some massive weight gain is headed your way this week whether you want it or not. If you were unable to gain during your first trimester or you even lost some ounces, the second trimester would make it up to your body and leave some extra.

 There is even the possibility of exceeding the limit, so you would need to pay special attention to how you eat.

Your baby is growing a lot bigger in the second trimester, so you would too. However, with the right dieting, you should be able to maintain a steady weight gain of about 1 pound every week.

Also, alternating it by gaining half a pound one week, and one and a half pounds the next week is alright. Provided you’re hitting the benchmark of a maximum of 4 pounds in a month, you’re perfectly fine.

If you’re monitoring your weight at home, ensure that you’re doing it under the same conditions at all times. Checking once or twice a week is more than enough and you can always check right after you get out of bed.

This way, there would be no extra weight from the food you would have consumed if you weighed later in the day. You could also leave your weigh-ins to your doctor during your scheduled monthly appointments.  

2.   Bleeding Gums

A good look in the mirror might draw your attention to red, swollen gums that may be sore, pretty sensitive, and may likely bleed when you brush or floss.

And just as you’ve probably, the blame lies at the feet of ‘em nasty (amazing) pregnancy hormones.

This time, they may have triggered gingivitis, an infection and inflammation that affects the gums and changes their reaction to the bacteria in plaque.

If you do not take special care of your teeth during this period, the gingivitis is likely to progress and result in periodontitis — an infection of the tissues and bones supporting the teeth. Furthermore, research has shown a link between periodontitis, preeclampsia, and premature labor.

What is a little more alarming is what can happen if you don’t take care of your teeth while you’re expecting. Gingivitis can progress to an infection of the bones and tissues supporting your teeth called periodontitis — and research has shown a link between periodontitis, premature labor, and preeclampsia.

 Prevention is by paying close attention to your dental health. Maintain good oral hygiene including brushing at least twice a day and mild flossing at least once a day. This would reduce the symptoms associated with gingivitis.

In addition, the hormones might likely make you experience nosebleeds or a chronic stuffy nose. And if you look closely enough, you might notice a minute lump on your gums that is known as the pregnancy tumor.

No need to worry, it is a benign growth with a scary name and is completely painless and harmless. If you’ve got one, it would disappear on its own after delivery.

3.   Heartburn and Indigestion

Recall that your appetite comes back this trimester, so you may be tempted to consume large amounts of food in a single seating. This may result in indigestion or heartburn so that you end up constipated.

A great way to avoid gastrointestinal discomfort is to consume your meal in small portions all through the day instead of the three major meals at once. This way, your digestive system would perform more efficiently.

Also, these symptoms can be caused by hormones as well. You’re still not above certain food causing you digestive problems, so you should steer clear of food that may serve as triggers. Have stomach remedies handy as well as antacids which are known for their high calcium content.

4.   Round Ligament Pain

You may notice some pain originating from around the lower region of your belly and this is known as round ligament pain. It occurs as a result of stretching in the muscles and ligaments that are supporting your growing uterus.

Now, while this pain is one of those things that you would just have to get through, don’t hesitate to contact your doctor if it gets too severe.

Measures To Begin To Observe

1.   Ensure That You’re Getting Sufficient Calcium

Ensure that you’re getting sufficient calcium because your baby would be needing lots of it. Your baby’s bones are starting to ossify and at this point, calcium is very essential.

 So, you should consume foods right in calcium, and including supplements in your diet can easily supply the extra. 

2.   Schedule a Dentist Appointment

A visit to the dentist may be the last thing that you want to do at the moment, but in the interest of you and your baby, you really should schedule that appointment.

Good care of your teeth is one of the aspects of any healthy pregnancy. Also, women who get gingivitis while pregnant are predisposed to complications such as preterm birth. 

3.   Stay Safe & Healthy

Changes to your diet need not be constant, but they are required sometimes. While you added some things and took away others in the previous weeks, this week might see you taking away as well. This is in a bid for you to stay healthy and trim.

Also, exercise is advised during pregnancy, but at 15 weeks, you shouldn’t be doing anything extreme. Avoid sports where you run the risk of heavy falls or bumping into people.


Carefully select the activities that you would be engaging in this week so that you don’t predispose your baby to harm from physical injuries to you.
