ovulation issues anyone?!?!??

Heather • Baby Girl coming June 26th 2016🎀🤰🏽
I've been using ovulation kits for about two months now, and this month I took the tests and I ovulated on the 12th. Today my blood work came back from OB/GYN and she said that I did NOT ovulate this month. i'm so so confused, highly upset and just plain old sad! Has anyone else gone through this before? What was recommended or what did you do, etc? I totally feel like this is all on me it's all my fault that we cannot conceive and I'm really just down in the dumps
