Not ovulating?

Ashlea • 27 years old... Married the love of my life 5.20.15 and gained 3 amazing step kids, baby #1 due May 2017
Do for the past 2 months my OPKs never were fully positive, the second line never ended up becoming as dark as the first but there was always at least a line and now this month I'm not getting any second line at all. Anyone else have this happen? Anyone have any ideas? Just recently moved to a new state and haven't been able to find a new doctor yet
