Why me? (A rant)

After months of trying I'm driving myself insane. I feel like I don't even know my body anymore! Between temp charts, cervical position and mucus I just don't know what to do anymore.! I'm soon to be 19 (if you don't have anything nice to say keep it to yourself) and it seems like all of friends who weren't even trying just got pregnant. I don't even want to log onto fb anymore it's just a stream of baby pics. My husbands family keeps asking and I've run out of things to tell them. No one understands how much I want this they think we just aren't "doing it right" ... So this is my very long rant of pity and sadness and disappointment. After this I'll go back to being positive and trying to ignore the whole "trying" phase. But if anybody knows what I'm going through it is more then likey all of you lovely people.
