OPK results + my doctors expression 😞

CC • 🌸 Mommy to Sydney 🙏🏻 TTC baby #2
I started using a 20 day OPK kit 2 days after AF ended - to my surprise I got 2 dark lines. I went to my Dr today and told him what my results looked like. He's under the impression that I should be ovulating on 7/18 based on the last day of my cycle and has me coming in for a blood test. This is my 1st month TTC and my Drs facial expression why I told him about the positive LH surge result looked perplexed. Is there something wrong with me? Anybody out the get +LH surge results, but you just don't ovulate? I keep testing and finally today my LH surge test line has lightened up. I'm worried that we are doomed from the start 🙁 does anyone have a similar experience or some words of wisdom for me? 🙏🏼 I've never felt more afraid for a blood test in my life
