Help!!! So confused!

Shawna
Please help, I'm so confused! I finally, just this month starting <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> with OPKs. Actually the 5th to be exact. Well anyway.. the test on the 5th was neg- barely a second line, the morning of the 6th I got a dark positive, so of course we BDd. Took another the night of the 6th, still bright positive. Morning of the 7th, still just as dark. Well I just took another for the hell of it, and guess what? Yep, still positive. What is going on? I thought you only got a positive for 24 hours or so? I thought I did really good this month but now I'm just confused and worried. Please help!
