Time is running out officially

I'm 42. Been together for 12 years. . We got surprised pregnant last October and miscarried at 3 months. Now we are really trying. Were in between stages of naturopath doctor and fertility clinic. Need to take the plunge to all the big stuff.....its so hard mentally.im scared of all that. We may be happy together childless but both want a family so bad..I have major baby fever since miscarriage:(
