Should I be annoyed or do I need to get my hormones in check?

Caitlin • I`m a married 30 y/o high school digital integration specialist. My husband and I welcomed our rainbow baby into the world 1/2017 and are excited to prepare to expand our family in the next few months.
We are due with our first baby 1/20 after suffering 2 chemical pregnancies last year. I just found out last week that my cousin is due 1/1 and I am very excited for her. She lost a pregnancy in 2014 and had a beautiful baby boy the following year. However, I'm a little annoyed because she posted her announcement a couple days after we posted ours. I understand that she is further along than we are and we did post our announcement a little on the early side but I was 9w4d when I posted it after 2 ultrasounds that we heard the heartbeat with. Should I be as frustrated as I feel?
