21, married

Hey ladies. My husband and I have been together 6 years married for 1. I am 21, almost 22, he's gonna be 24. We live on our own, support ourselves financially with NO problem. We are both on the same page about having children. We've been ttc for 2 1/2 years (no luck). The only problem is, I can't really talk to my mom about this situation. She does not think I am old enough to have children, even though by 21 she had 2, who she could NOT care for financially at all. She feels like my dad would 'freak out' because she doesn't think he'd be able to accept that fact that he's 46. My father left when I was 5/6, only talk to him when I make the effort, not him. Do you guys have any advice on how I could tell her I am trying to have a baby? I know I'm an adult, I can make my own decisions, and it's not her choice but I feel like maybe she's the one who couldn't accept that she's 43 and would be a grandmother. I just want to be able to talk to my mother about this kind of stuff but don't know how to approach the situation. Also, any ideas on how to tell a 'strict' dad your pregnant?(for future) thank you ladies, I appreciate it!!
