If its a Retroverted uterus, I have the same problem. When I went for my 6 week check up after giving birth to my son the nurse told me it had gone retroverted, pregnancy being the cause in my case. It can also be casued by endometrosis or you could have just been born that way.

The main issue I have with it is some intercourse positions hurt and its also know to cause more period pain.

Here's a link to some information about it

Retroverted uterus info below from this link

A retroverted uterus means the uterus is tipped backwards so that it aims towards the rectum instead of forward towards the belly.

Some women may experience symptoms including painful sex.

In most cases, a retroverted uterus won’t cause any problems during pregnancy.

Treatment options include exercises, a pessary or surgery.
