It really varies with women. The first time I got pregnant it was in high school by "accident" Unfortunately I had a miscarriage. When I wanted to get pregnant in my 30's we tried over and over with no luck. It really depends on age and hormonal balance and a lot of other factors. Having sex every other night is a good idea. Most couples can get pregnant within a year, often much sooner. Two months of trying is not very long though.
Meanwhile enjoy the process and learn to love sex. It will serve you well for many years and just let it happen. My aunt once told me that a watched pot never boils. I think if you relax and just enjoy making love it will happen
