Am I a bad person?

My sister is pregnant and I’m going to become an auntie but I’ve also found out that a girl we grew up with and is basically family is pregnant and they’re due the same day. I can’t help but get upset and feel down when it’s talked about as I’ve had 2 miscarriages and been trying to conceive for over a year now, I should of had my baby the 10th June. My mum is really exited for a granchild but when I told her I was pregnant she got really upset saying I’m too young and none of the family really spoke to me for a while but I ended up having a miscarriage. I haven’t told anyone about this but am I a bad person for feeling like this and not being completely happy to be an auntie?
