Length of Menstrual Cycle and Fertility

Karen • Married in 2012.
Is there a correlation between the length of your menstrual cycle and your likelihood of infertility? I'm 34 years old and my Menstrual Cycle has been pretty consistent at 28-29 day cycles. However my last 2 cycles have been 32 days long. I've been trying to conceive baby #1 for 19 months now.
