trying for first at 36

Good morning ladies. I am trying for my first child at 36 will be 37 in september. We waited because we never have enough money to justify it. But now I am old (well in childrearing years). I am in a good place now and our marriage is stronger than ever. I am nervous about the results. I just started charting my temps and checking cm. This month will be my first full cycle. We haven't been preventing for months. Prior to this I had so many months where I thought I might be pregnant. I plan on charting a few months then going to the dr to see what they think. I have a fertility stick that came free with my pg tests that tests egg reserve that I will be doing tomorrow on my cd3 but I don't know how accurate those are but it came free so I will try it out. I am excited and nervous at the same time about this experience. I just hope its not too late. I am the only sister out of 4 without kids. It can be depressing at times. I've been asked if I can have children and to be honest I don't know the answer. It's makes me uncomfortable. I am sooo ready but I know I need to be patient.
