See infertility doc: At your age, every few months of more time not getting pregnant is important. You should see an infertility specialist soon for some tests.

2 more months: We usually tell couples to try for 12 months. The conception rate is 15 percent per month, so 85 out of 100 couples will have a positive pregnancy test. After that, it is reasonable to have your gyn examine you and recommend appropriate testing. Also remember, men have an equal chance of having fertility problems, so one of the first things to do is a semen analysis as this is the least invasiv.
