Just don’t know.....

Me and my fiancé have been trying for a few months to get pregnant and just about a month ago I gave up and haven’t really been trying. Just having fun. I have a 3 year old son. And I really want another baby. I lost my second baby. My baby girl at 15 weeks last year and I just want to have another baby. And be able to make him a dad. Like he so wants. I don’t know why I can’t get pregnant. Or why it won’t happen I’m just at a loss for words ans just feel like I wanna give up and stop the whole thing. But I can’t. I just so badly want to be pregnant. And it just won’t freaking happen !! I’m sorry so long. Just wish I would have a baby already. Lol.
