How Big Is a Baby at 15 Weeks Pregnant?

At 15 weeks pregnant, baby is as big as an Apple. The average 15 week fetus weighs 2.5 ounces and measures 9.3 to 10 cm or 3.7 to 4 inches, baby’s proportions are becoming even more normal, since his or her legs now out-measure the arms.

15 Weeks Pregnant Symptoms.

Shortness of breath: Your uterus is growing quickly, therefore it might be difficult for your lungs to expand enough to get a full breath, that’s normal, get use to this symptom because is just starting mainly if you are expecting twins.

Swollen gums: Your gums are more sensitive now that you’re pregnant. Take extra good care of them. Brush your teeth often, floss gently, and see your dentist for regular checkups.

Nosebleeds: This symptom is thanks to a combination of increased blood volume and sensitive nasal passages.

Increased sex drive: Now that your energy is back, you may be feeling more energetic in the bedroom as well. Take advantage of this time of romance and happiness but in case that you don’t want is understandable too, communication with your partner is key, let him know how you feel.

Heartburn, gas and/or indigestion: Blame these tummy troubles on the hormones. Pay attention to foods that are triggering your symptoms and try to avoid them. Also, talk to your doctor about what stomach remedies are safe.

What is happening with your baby?

Your baby’s skin is very thin, and the blood vessels can actually be seen through the skin. Your baby’s ears are continuing to develop externally and look more recognizable. 

The baby’s bones are beginning to ossify, meaning that all bone structures are more visible.

Tips for you at 15 weeks

Many women have questions about sleeping positions while pregnant, well here is a little tip for you, It is best to begin sleeping on your side. This is the most comfortable and healthy sleeping position. Sleeping on your back causes your uterus to place pressure on the aorta and inferior Vena Cava, which supplies blood to your lower body and the baby.

Typically, there isn’t a 15 week ultrasound. You likely had an ultrasound in your first trimester and won’t have one again until the anatomy scan, which usually happens between weeks 18 and 22.

There are possible reasons why the doctor order an Ultrasound at this time:

  • Excessive pelvic pain or cramping.
  • Spotting or bleeding.
  • Traumatic event ( car accident etc..)

If any of those symptoms occurred doesn’t mean that necessarily there is something wrong however is always good to check.

15 week Ultrasound can be performed Transabdominally or Transvaginally, and here is a glimpse of what you can expect to see….

This ultrasound images are generally speaking what you are expected to see, all ultrasound doesn’t show the same and it all depends on multiple factors like Fetal position, maternal obesity etc… If you don’t have those views on your scan is ok, as long as the development of your baby is normal and the measurements are compatible with the gestational age is all good.

OK, thanks for staying with me until the end, on my next post I will be talking about 16 week ultrasound, thank you for visiting my blog today, I will love to have you back another time.

  1. where were you when i was pregnant! love it

  2. Deciding if it was a good idea or not to make this blog, honestly I was terrified of everything but with comments like yours I see that my blog was a good idea, thanks for your feedback, that keeps me motivated

  3. Blogs like this are a nice break from the “oh so serious” handouts and text books most women are forced to read, because there isn’t enough personal information on the internet. This brings a more friendly and welcoming vibe to the subject. Never doubt your niche! Why did I think of this 🙂

  4. Thanks
