My aunt in pregnant!!!! 😢😢

So I just received a message from my aunt saying she is pregnant...she already has an 18 year old...and 11 year old and a 4 year old and expecting and said she didn't expect it. I'm super happy for her because I've been telling her to have another baby to see if she has a girl cause the other 3 are all boys. I can't help it and feel sad...I got my period 5 days earlier and this message 😢😢 I've been trying to conceive for the past 9 months with no luck. Nobody in my family knows we are trying and it's so frustrating. Just need it to vent a little I also don't want my husband to see I'm upset I don't want to put pressure on him.
