Hurting my parents feelings by not having kids when both of them are childfree

I am 17. I am not 100% sure if I will have kids but I don’t want to, I am just not sure if I’d be ready to have kids soon. There are many reasons why I don’t want to have kids, they’re very personal to me. My parents had me when they were around 40 and I know that they don’t want me to have kids, they told me this multiple times. However, I know that they will be very hurt if I don’t have kids because they don’t want to be childfree forever. I’m just really confused on what to do.<br><br>Note: I don’t want kids but I’m not sure if I’m sure about this<br><br>Edit for context: I was born via surrogacy and my mom is infertile. She was very stressed about not being able to have kids and I had to work very hard to have a child. She will be very hurt and feel like she wasted her time and money if I don’t have a child (she won’t be able to see her grandkids)<br><br>That’s why my parents don’t want me to have kids, because they know how painful infertility is and they don’t want me to experience that.<br><br>I get that both of my parents are hurt over this and I want to help them. I just don’t want kids because of personal reasons. But I feel like I’m hurting them if I don’t have kids.
