I Was Diganosed With Endometrois Back In 1997, I Got

I was diganosed with endometrois back in 1997, I got pregnant with my 2nd child shortly after but when he was born I was told that it should be gone with the pregnancy. Well, in 2004 I had a partial hystercomy where the ob-gyn removed my uterus. Can endometrois reoccur? Also, I have a line of relatives with endometrois on my mom's side.
