Ttc baby #2

Shelby
Me and my hubby are getting married in april 2015 and we really wanna have another baby it took us almost a year and failed birth control to conceive our daughter now she is almost 2 and we have been trying for 6 months to have baby #2 and we have sex on all the fertile days and this month we tried every other day on our fertile window im not on birth control and I did get one depo shot after my daughter was born but never got it again cause I hated the way it made me feel and I dont know if thats the reason im not conceiving but seeing the dissapointment on my fiances face every month is heartbreaking and im starting to believe we arent meant to have another baby any tips on ways to help us conceive would be greatly appreciated
