32 TTC after miscarriage

I have had very healthy pregnancies with both of my boys (10 & 12). So when we TTC for our third and got pregnant we were so excited. Sadly in November at 6 weeks I had a miscarriage. I was devistated. So we have decided to try again but I'm starting to get discouraged because I'm not getting pregnant. Any of you guys gone through this and what are have to done to increase your chance of getting pregnant?
