Should I feel bad?

So last week my husbands cousin had a miscarriage. 
Well, today, we had an ultrasound and found out we're expecting a little girl! I was so excited and I sent his aunt a text and picture to tell her. 
All she said was "That's wonderful. Did you know *cousin* had a miscarriage last week? She's really upset" 
Well I already posted a bunch of pics on Facebook and announced its a girl. 
I feel bad, because I seriously wasn't thinking. Buy I'm also upset that this women always says we don't keep her updated, then when I tell her, she just acts like its no big deal. And I feel like she's trying to make me feel bad.
