am I a bad person?

Carly
So...
Me and my boyfriend of 6 years found out we are pregnant after I was told I could not have children and we are really excited and everyone else is for us! We told our families and I am now currently nearly 9 weeks. When we told his mum she said she was jealous,she has a 1 year old also. We told her when I just found out at 3 weeks as we are all really close. The other day she did a test and found out she is pregnant now also. She is around 1 month behind me in the pregnancy. She is really excited that we will go through this together. But honestly I'm a little upset I know it sounds selfish but  yeah In a way I'm excited but when I first found out I was a little hurt because it kind of feels like it was done on purpose to share the limelight. The moment I mean within seconds she found out she was talking about all the things we can do together such as maternity shoots and everything. I don't know what's wrong with me and why I'm not super excited like she is? I think I may be a little embarrassed. Is it wrong for me to feel like this???? 
UPDATE- 
So I'm also on another group for the baby, and she has been posting nasty comments and me and my boyfriend her son, it's really upsetting me x
