Does uterine fibroids relate to pregnancy?

yes. they can grow along with your periods and may also grow along with your pregnancy. usally they do not cause any complications during the pregnancy but a small proportion is associated with abortion. consult your obstetrician.

Have a look at this web page, talk it through with your doctor.

No doctor here, so take what I say with a grain of salt and ask a doctor. In the past, uterine fibroids were sometimes treated by a hysterectomy. That definitely relates to pregnancy if you are still in child bearing years. Current treatment can often be done using embolization to reduce the size of the fibroids.
