I know what you mean! I will be 27 on Monday and I feel like I should have already had a baby. My mother had me when she was 21 and I liked having a young mom growing up.
However... For me even a year makes a big difference in my maturity level, my patience, etc. my husband and I have been married for almost two years now but I like the idea of waiting a little longer to focus on us. I'm hoping that by 30 we start trying for kids. Hell, I have so much I want to do after I lose this weight and I don't want kids to stop me lol so I say wait, enjoy your husband, and enjoy yourself as you lose weight and get healthy
