Frustrated and upset

Melissa
I have 2 children a boy and girl took me 3 years to get pregnant with my last. I'm really wanting another. Went 4 days late on my AF and today I get it. I had a lot of pregnancy aymptoms. I'm very upset and frustrated because all my FB friends are posting new pregnancies. Upset to the point I want to remove them and give up trying. Anyone have any words to help? Much appreciated.
