I know what you're going through also, I'm 36 and have been trying for almost 20 yrs, my doctor told me that I don't ovulate, Well needless to say that I had a miscarriage on June 22,2007. I did not know that I was pregnant, I guess because I never thought It would happen.
But I would be about 6 months along if I would have carried it, and so far no pregnancy yet.
I took Chaste Berry (vitex) for about 1 1/2 months, that may have helped, plus I cut out the caffeine. So maybe we just need to think positive, and pray every night before going to sleep.
One day the Lord will bless us with our miracle.
Hang in there.
Sincerely
Tammy
