Am I being selfish?

Ashley

My husband and I have been married for 3 and a half years. We both wanted children and talked about it before we got married. Everyone that we know is pregnant and I get emotional about it. I want to be a mom and I just turned 30 this year and I feel like my clock is ticking even more. I don’t know how to talk to my husband about this. He says he still wants kids but idk if that’s true as every-time I bring up the subject he changes the topic or just says we will one day. Idk any help would be appreciated.
