A stupid waste of a month

Been trying to conceive for 13 months now. I was on depo and that's made it really hard for me. I get really hyped up after my period thinking this is it..this is my month then 1 week before af my boobs swell and my emotions go over top. I'm starting to get depressed now and thinking its not happening because I'm probably not supposed to have a family. Really am starting to feel down. The sight of my period and I go angry and upset. I like to come on here and see all bfps and positive stories about pregnancy but then closer to af I start to get jelous and upset.
