2 Positive Ovulation Sticks 3 Days Apart

Mon, Tues, and Wednesday my ovulation tests were negative.  Thursday it was positive.  Friday it was negative (which I expected), Saturday I didn't take the test.  This morning (Sunday) it was positive again.  Any ideas what would cause this?

I'm not sure unless the test u hve r faulty. Or u ovulated twice. What type of opks r u using bcuz the ones with the lines should b dark lines or equal( the control & test lines)

Here's what I was thinking...the OPKs with the lines can be very hard to read sometimes.  My line is usually SO faint or non-existent compared to the control line so anytime I see it being relatively dark I assume I O'd...or am about to.  Is there any way you mis-read one of the two tests?  Just to make sure you covered all your bases, did you BD the first time you saw the line?  And I'd make sure you BD a bunch now too...Good luck!
