Ideally it is said that a couple can try naturally for a year before seeking help for pregnancy and should visit a doctor earlier i.e after six months if female partner is more than 35yrs of age. Age criteria is specifically mentioned for women and not men .But this is not the golden rule. We find that couples may need early intervention at times.
I would suggest that instead of waiting best get your basic evaluation done which includes tests to check ovarian reserve , tubal status and husband’s Semen analysis ..know your parameters and if all is normal ask the doctor for how long you can try naturally.
This will reduce your anxiety and you will understand the process better.
