Military wife

Sometimes it gets really hard. (Trying to get pregnant ) he is always gone. And when he is home my period is here. Haha. We have had unprotected sex since highschool. And never ended up pregnant. That's been almost 5 years. And now that we want to still no luck. Do you guys think that I should see a doctor about it. Even if he is deployed or wait till he comes home and do it together?
