Why is this so hard??!?

Let me start off by saying that I have 2 kids. I had my daughter when I was young (17) and it took me 5 years after having her to have my son. I have found an amazing man now and am married and now have baby fever lol. My husband and I have not been actively trying but haven't used any precaution against it. We have been together a year and no BFP!! :/ I really thought this was our month and had gotten a faint positive and then af showed her ugly face this morning :/ why is this soooo hard? Ugh!!!!
