Ttc but having an emotional roller coaster

Kristi
My husband and I are ttc. We have just started trying within the past 2 weeks. I am very nervous!!! I have a 3 year old daughter with no complications. December 2013 I had a miscarriage and exactly a year later, December 2014, I had another miscarriage. I want to conceive so bad...... I have read so many different things telling me when I will be ovulating. They all have different answers. What is the best way to know when you are most fertile and more likely to get pregnant?
