Does birth control affect chances?

I got off birth control pills in September and my husband and I have been TTC since then. Every month since then has been so disappointing every time I have my period. And I have a long cycle, so it's even more frustrating because it's a long wait. I keep getting my hopes up and then...period. Before I stopped taking my birth control, I had been on them for 8 years. Could it be that my body is still not back to normal yet from all the years of trying not to get pregnant? I need help ladies! Any suggestions are welcome too.
