The Uterus in Pregnancy


Hey there!

This is Dr Manu, consultant Gynecologist in Chennai

At the outset, I would like to welcome you to Dr Manu’s Gynecology Clinic. So, in this blog post we are going to discuss about uterus size during pregnancy. I know a lot of you have a LOTS of questions regarding this topic, so take a deep breath and start reading!

So, the uterus is usually quite small and lies pretty deep within the pelvis. The uterus is basically collapsed cavity (I am sure you did not know that?). The uterus grows exponentially larger with increasing weeks of the pregnancy (to accommodate the baby)

The uterus size during the 1st trimester of pregnancy

At about close to around the 3 month of pregnancy your uterus starts growing up out of the pelvis. In the event you are carrying twins, the uterus can be slightly larger and can felt by your gynecologist through your skin.

Next with increasing weeks of the pregnancy, the uterus continues to grow. Eventually in the 5th -6th month, it comes out of the pelvis and pushes the navel outward. This is completely normal and there is nothing to be alarmed.

Experiencing mild aching pain in and around the lower abdomen is also the norm during this time. Your gynecologist will usually be able to measure the weeks of your pregnancy my estimating the fundal height.  The fundal height is usually measured from the pubic bone to the top of the uterus (called the fundus), hence fundal height. The fundal height correlates with the no of weeks of pregnancy. Say if your fundal height is about 28 cm, it would roughly correspond to 28 weeks of pregnancy

Interestingly, during these antenatal visits, if your uterus height is too small or too large, this could potentially mean a pregnancy complication. More testing and imaging studies is usually advised by the best Obstetrician and Gynecologist in chennai.

“Never Ignore a suspected pregnancy complication. Getting regular antenatal checks is a must”

The uterus size during the 3rd trimester of pregnancy

The uterus usually reaches its final size during the third trimester of pregnancy. It will extend almost from your pubis all the way to the rib cage.

Post delivery of your lovely little baby though, the uterus size will gradually return back to normal. This process is called involution and usually takes about 6-7 weeks .
