Should I be worried?

As
At the moment I'm 21 years old and seem to be healthy. But I have one worry that I'd really appreciate getting input on. 
My boyfriend and I plan on having kids when we are ready, and that won't be until we are in our late 20's to early 30's. The problem is the females in my family on my mothers side are prone to getting uteran cysts (or uterine fibroids), because of this they have to get hysterectomy's, and the few that have gotten it had it in their mid thirty mark. 
I'm just worried that I won't get to have children. My boyfriend and I REALLY want kids (2-4) and we aren't sure if it's possible with this possible problem. Does anyone have any personal experience with this or know how this affects having children (if it even does). Thank you!!
