Advice!

I feel guilty for feeling how I do but I'm 3 months pregnant and my bestfriend just found out she is pregnant. She's also my boyfriends sister so 2 babies in the family a couple months apart. Is it terrible that I feel annoyed to share my pregnancy? Ive wanted this for so long and she's not even that happy about it. And their family is my family and I feel as if my baby will be left out since she's having hers. Does this make me terrible? 😩
