That makes sense as a biochemical response to difficult times; kind of a built in birth control until the "time is right."
There's also the psychological side of this, which is like that old cliche about a watched pot never boiling. It does, in fact, boil, it just seems to take longer from the watcher's perspective because they're focused on it.
Also, please make sure you're getting the right vitamins for a pregnancy--folic acid in particular. I know, you probably know that already, but I honestly can't help myself.
