Worried.

Is a 37 day cycle normal? My cycles are normally longer (like 32-35 days sometimes) but this past cycle was a 37 day cycle. I take ovulation tests every month too and i ovulate every month according to the tests. We have been trying to conceive for almost 9 months. Could something be wrong with me? I was also on birth control for 7 years so could that be what’s going on (between not being able to conceive yet and having longer cycles etc.) help! Any advice is great!
