TTC after 2 miscarriages

My husband and I have been trying since my second miscarriage in October of 2013. The doctor put me on birth control till January then I was free to start trying again. The last few months have been really hard and we're trying to stay positive but it's so hard everytime we think this is the month and then we get a negitive test. How do you cope as a couple? And how do you stay positive?
