I know i have no right but

So my sister in law and brother are pregnant and due in the spring, I am now pregnant 10 weeks along and due in July we are announcing on Christmas. Today my other sister in law and brother announced they were pregnant and they are 8 weeks.I know they didn't know we will be announcing and i should be happy they didn't do it on Christmas but i feel like the stole my thunder! And we are due the same month. I know its stupid but I'm a little upset. Sorry just had to rant to someone.
