I’m worried I’m waiting too long...

So, long story short:

I’m 25 years old and have been with my boyfriend for 2 years. We aren’t interested in getting married or having children any time soon because it’s just not what we want at the moment. We want to travel, focus on us at the moment, etc.

However, I’m beginning to get worried because every female on my mother’s side has had to have a hysterectomy by the age of 27. I’m so, so, so worried because even though we don’t want to get married or have children now, I do want those things with him. He’s certainly the one. But I’m so incredibly worried we will miss our window of opportunity.
