It's impossible to tell without a full history and medical background.
This is really a question for your own medical practitioner.

So are you tracking your most fertile times and having sex just before that time.

Hi Diamond80000,

Frustrating when it doesn't happen as quickly as you think it should. It is important to keep in mind that it can often take many months, sometimes more than a year for some couples, to become pregnant. As was mentioned, be sure to track your cycle to determine when you are most likely to be ovulating. Being off by just a day even can make a difference.
Are you able to have frequent sex throughout your cycle? This can help with covering the timing, but timing is only part of it. This is partly why it can sometimes take quite a bit of time.
