Should I be offended?

I had a miscarriage in April and it's pretty obvious we're still trying for a baby and my sister in law past a comment about how Spanish people are so fertile (obvi, my husbands family is Spanish).... in my head I was just like "well that's great, sorry I'm not Spanish". Like the negative pregnancy tests make me feel like shit enough. You don't need to add to it. I just got the vibe she was rubbing it in my face because they have a lot of kids and I'm having trouble making one 😤😩
