my hope is still there at 43

Hi, my name is lorrie. And i am 43 years old. I am new to this whole thing. And i am afraid, it might be to late for me to conceive. I have all the will, and hope in the world though. I have a fiance. we have been together for seven years, and engaged for three years.We both want a baby more than anything in the world. Our hearts ache, even though we try not to show it. We both end up in eachothers arms. each month my cycle comes. He nor i have ever had children. He is younger than i am. Not that it matters, his age i mean. But i was told that the age difference might help us to conceive. We have been trying for a year this past july with no results. I cant afford it, but i cant afford not to. But to see a fertility dr.(@ 290.00 for the first visit.) In march, and even than. i am nervous that hes going to tell me, my door has closed. The only test i have right now is blood work from my g.y.n. a hormone level of some kind. They ran it last july. They told me that my levels or points did not indicate that i was perimenopause. So i thank God for that. But than the dr. also said that they really couldnt tell much from that kind of panel. So been ttc 20 months in, on the old ovulation scale. and in home ovulation test's. So i am really concerned and nervous. My heart goes out to anyone who wants a baby more than anything. So i cant wait for march to come till my endro. appointment, and thats about where i am right now in this journey. And who ever might read this "Good Luck" and dont give up your dreams.
