Positive OPK for 11 days, day before Period due?!

[Lemonly]

So confused! I have had a solid positive OPK for 11 days now! My husband has a vasectomy, he is getting it reversed in April so I decided to start tracking my cycle so we're ready when the time comes! But I just don't get it! I'm due for AF tomorrow and the test is still positive! I would post a pic but I have no idea how to do it on here! I took a pregnancy test 5 days ago and it was a BFN, no surprise since my poor man is still snipped. But something must be up, right?

Is the test line darker than the control?

Yes, very much so. One day they were around the same color, so I was thinking maybe I should consider it a negative, but then I took the test again 2 hrs later and it was back to the same very dark color.

First thing in the morning I think you should test for pregnancy!
