Too soon to tell parents?

Hi! I’m 37 and this will be our first baby. After missing my period last week, we just found out we are pregnant (5+2 currently). I am very close with my parents and they don’t live near us, and I’d prefer to tell them in person. We are seeing them tonight and I dont think we will see them again for at least another month… so I’m feeling like I want to tell them! We leave this week for a 2 week trip, so I won’t be seeing my doctor until after the trip as well.

Part of me wants to wait til we have our doctor appt but I am so excited and it will be so difficult not to share with my mom. Do you think it’s too early to share with just our parents? I think part of me is being cautious with constantly feeling worried about age being a risk factor.

This baby wont be my parents first grandkid, and if something happened I’d absolutely want their support. Did anyone here share early and regret it?
