Well said Jazz.
As Jazz said earlier, you must stop trying.. and continue to go with the flow. Just start acting like you used to when you were both dating each other.
Have fun, be carefree, enjoy life.
Any bit of doubt or stress, changes your bodies chemistry and biology, which in turn makes it difficult to become fertile.
If you even have a stressful job, will make an impact on your bodies chemistry, this includes the both of you.
Even not eating the right foods will do the same.
In my opinion, it would be silly, for your body to let you be pregnant, if your body was not ready for it biologically.
At the moment you might be mentally ready, but your bodies say otherwise.
Years ago, I posted about helping your body get ready for pregnancy here:
Having said all that, I do feel you getting pregnant late next year, and having a boy.
