Feel like giving up

Been TTC for 10 months. Last week I found out I had 2 cysts and they burst.. AF came yesterday. We have used pre seed, we bd every other day. And I take vitamins daily. This week.. Every day I get on Facebook someone is getting pregnant, and its not even the girls that were trying! Its the girls younger than me, that don't have stable relationships and I don't wanna be rude about it, I'm glad for them I just feel like its time to give up.
