Having TWO uteruses and cervixes – An Anatomy Anomaly

Have you ever heard of someone being pregnant but never noticing because they still had a period? How about someone who was pregnant but conceived again while pregnant, carrying two babies? It is possible! There are many variables that could cause this to happen. Today, we are going to talk about a few uterus variations!


There are many variations of Uterus. One of the most common congenital anomalies would be a biocornuate uterus, otherwise known as a heart shaped uterus! It is estimated that a bicornuate uterus is seen in 1-5/1,000 women. You very well may know someone personally that has a heart shaped uterus. There are many different variations of bicornuate uterus though. Some more severe than others. It can increase pregnancy and birth complications but most go on to deliver perfectly healthy babies!

There is also what is called a didelphys uterus! This is where there are TWO wombs! This is one way a woman could be pregnant but still have a period the entire pregnancy. This isn’t super common, many might not even know this is possible! Statistics say that 1 in every 3,000 people women will have a didelphys uterus.

With a double uterus, there is also a double cervix, as shown above. YES – 2 cervixes!

A didelphys uterus can be either unicollis, with 1 vagina OR bicollis, with 2 separate vaginas! Yes, a woman can have 2 vaginas! Many with this anomaly do not realize this until they begin menstruating and notice that they still bled after inserting a tampon into their vagina. They continue to bleed because it is the OTHER vagina that is bleeding! Another reason a woman could be pregnant and still have a period her entire pregnancy, leaving her unaware of conception.

These uterine anomalies are the result of the Mullerian Duct failing to fuse correctly when the female is developing in her mother’s womb. There is no known cause of this at the current time. There are many different variations of uteri that haven’t been covered in this short blog, but it is interesting to see (in the image below) how many variations there are!
