TTC for two months... Help, please?

My fiance and I have been trying for two months to get pregnant. He is leaving for Afghanistan in May or June and we would really like to conceive a child before he leaves. We "baby dance" almost everyday, which sounds kind of bad, but its true. We have been taking fertility supplements since New years Eve so maybe they will help... But I am ready for my BFP!!! I really need help... We have tried the propping my legs up afterwards. We have tried what seems like everything... Can anyone help? I am open to try anything, so please let me know of any natural remedies or positions or what to do afterwards....? Thanks!
