Aggravating SO family members.

Mary • I`m Mary Edmonds, I`m about to be a nurse, I love my cats, Netflix and would die if I had to do something I hated.
Okay, so my S/O and I had gotten engaged December  23rd of 2015. Ever since then, his mom, step mom, grandmother, uncle everyone ask me, "When are you two going to have children?" I mean it's like my empty uterus is the talk of the town. Now mind you, I am no where near ready for a child, and they know this but the keep on asking me. It's getting rather annoying. Then today, I had post a status yesterday saying I was feeling sick, his step-father comments, "pregnant?" Like no????? My womb is very much empty. Then, as the conversation continues via this status, his cousin (who married into the family) told me they only want me to have a child so I'll be "trapped in the family" and that I need to, "wait as long as I possibly can". Someone please give me advice on how to get these people OFF MY BACK. 😤😤😤😤
