I shouldn’t feel guilty for wanting a family

So I just got married in The beginning of February, we’ve been together 9 years tho. I really want to start trying to conceive but am constantly shit from my one best friend. Her wedding is in November and she is giving me a hard time that what if I go into labor and I’m not there. And how would I feel if I had a 9 month pregnant girl in my wedding. Which I did have a pregnant friend in my wedding even tho she was 5 months. I have another best friend getting married a week or two after her and while she jokes around she doesn’t care if I’m pregnant for her wedding. She makes me feel awful for wanting to start a family with my husband, I’m going to be 29 in August I don’t want to wait forever. Am I wrong? Should I wait?!
