Is this a positive OPK?

[amphibology29]

I tossed my OPKs from yesterday and today, thinking it was negative, and DH took the trash out already, but then I started thinking it might have been positive. So I searched through pictures and found some OPKs that look just like mine did this afternoon.

Again, these are not mine, but look just like mine did! http://www.fertilityfriend.com/tg/entry/7613589.html

Yesterday's test line was nearly nonexistent, and this evening's was as well. But this afternoon I had a test that looked like those pictured above. I thought it was negative since the line wasn't darker than the control line, but I found that picture in the Positive OPK gallery. Since my OPKs were clearly negative yesterday and again this evening, is it possible that was my positive this afternoon, and that's all I was going to get? (There were about 4 hours between tests today.)

Here are links to my charts (I use two different websites), for further reference:

I'd think based on your chart with the temp drop that it will go up tomorrow so yes possible + opk!!

It looks pretty close to positive.

I feel like I keep repeating this, but the temperature drop is not an indication of ANYTHING. You want to see the SUSTAINED RISE after a +OPK, which indicates ovulation has happened.

http://www.fertilityfriend.com/home/e2388 - here are a couple of my charts. Look at the cycle that I conceived DD - no dip. Also, fertility books will also mention this and saw it's caused by a surge of estrogen, but it is not necessarily indicative of impending ovulation.
