Too sensitive?

Hey everyone 
I had a miscarriage 24th July, it was only early we was only 5 weeks, but still doesn't change the fact we lost our precious baby #2. 
The only people we told was our close  family, so parents, siblings & partners that's it. 
The day after my brothers girlfriend decides to tell me she's having pregnancy symptoms and they've been really trying since she found out I was pregnant and she's convinced this will be their month! 
I'm not that close to her so for her to keep texting me is out or character and I feel like so hurt that she's doing this when she knows I've just lost a child? X
