My mom sent me pictures of my cousin’s baby after my miscarriage...

So I had a miscarriage a little less then a month ago, with a d and c little over two weeks ago. So everything is still fresh. My mom went to a family event that I was invited to, but decided against going. A cousin of mind just had her baby about two months ago and my mom sent me two pictures of the baby and said aww look at this baby! She’s so small and adorable! And yes, my mom knows about everything. Is it wrong that I’m upset about this? I just sent her a heart and didn’t say anything. I told my husband and he’s upset about it, says I should say something. But I think I should just let it go. What do you all think?
