Should I be offended?

Mr

Any time I mention to certain people I want to TTC they talk to me as if I’m unaware of the duties of parenthood and say that I should wait. I’m getting married in APRIL!

People who have known me for a long time know being a mother was something I have always wanted for my future. I understand I cannot please everyone but these are people who I care about and I’m close to. What do I say without just walking away from this awkward conversation?
