Maybe I'm being Petty....

So yesterday was my moms birthday and we always go out to dinner. Well my brother and his new gf came and they brought her baby (he's not the father btw). All night my mom was just like "well if I had a grandbaby" and "when u finally decide to give me grandchildren" it really upset me because it's not like I'm not trying. She didn't mean anything by it I don't think bc she doesn't know we've been trying since November/December. But it still upsets that she would say that. Am I being Petty or is it reasonable to feel that way?
