Running into walls

I know this is gonna come across as dramatic- after all I've been trying since January- I've also only had two cycles and it's April- but I feel like there's no way I'm every going to be pregnant. And I know it's me that would be broken, as he has been proven to have quite capable sperm. It scares me, because as long as I can remember I've wanted a baby. Not just a baby, a child of my own. I've spent my entire life taking care of everyone else's children, but now I would like to take care of my own. Any advice? Positive thoughts? Feeling rather crushed.
