Feeling discouraged

Starting to get discouraged in my attempt to ttc baby #1. My husband and I are high school sweet hearts and have been together for 9 years, 8 of which I was on the pill. So after two fun years of marriage we are ready to share our love and have a baby. I stopped the pill July 2017 and we started trying in August/September. But month after month I’m starting to get more and more discouraged and depressed every time a get a negative. Since I’ve been on the pill for so long I don’t remember what my normal cycle length was and I’m finding it bounce from 28 days to 40 days to even no period and me having to go on progesterone pills. I’m so confused!!! I’m average height, exercise on and off and of average weight so I feel I shouldn’t be having all these problems.

I guess I’m just frustrated being a week late with bfn and no indication when af is coming. Anyone else sorta in the same boat. Or anyone have any tips ??
