Thought I was ok, but I'm not

AF showed up right on time early yesterday morning. I was half expecting her to come but at the same time I was hoping she'd stay away. I actually ovulated this month which I definitely thought was a positive, but once again AF showed. Yesterday I was ok, today I'm an emotional, sobbing mess! We're now into our 11th month TTC and the stress is really getting to me. We're already seeing a fertility dr so there's a plan moving forward if I don't get pregnant with Clomid alone in the next few months. Honestly I'm just contemplating taking a break, but can I afford to lose anymore time?! What's freaking me out most is the cost of more invasive fertility treatments. DH and I want to buy a house and we can kiss that dream goodbye if we have to pay for fertility treatments. Don't know what to do anymore. I know a lot of you are in my shoes. How do you cope?!
