OPK line and vvvfl on pregnancy test after confirmed ovulation

Kaylen
Hey ladies-
The past few days I've felt different and have been (of course) noticing so many signs/symptoms. I am 9/10 DPO. I decided to cave and take a test. I purchased the packs of LH surge (OPK) sticks and HCG from Amazon. I grabbed both out and just ran them both. Here's the interesting thing - I had a vvvvfl on the pregnancy test right at the max time basically and the OPK came back with two strong lines (not like a positive OPK strong, though). 
What could be happening?!?
