Mother pregnant before me.. in my feels..

heaven

So, my husband and i have been ttc for about two months. My husband and i are 21 years old and have been married for almost two years without children. My mother and father are 40 years old, they have been married for 22 years with 6 children (now 7) . I get a text lastnight telling me that she is pregnant and now there is a good chance that my childs aunt/ uncle will be the same age as he/she is.. thoughts?? i only slept 3 hours lastnight crying because i wanted a baby and she is pregnant without trying. Yes, i know its jealousy and i am happy for her, i just wish it was me..
