I took another test this morning, which was probably dumb but oh well. I am feeling really...really menstrual today. So I'm not really hopeful at all. I felt sort of menstrual during early pregnancy before too, but still it just feels more like my period. So far no more bleeding today.
I use OPKs just about every month and have for quite some time, but I have no experience with that brand. They are quite helpful though. I have used internet cheapies almost exclusively and they are fine (they have lines kinda like a hpt but they are different in that it's only positive if the test line is as dark or darker than the control line. I've had a few internet cheapies that were hard to read because the test line would look half positive and half negative, but I think I read somewhere or somehow decided to treat those as positive. One time I forgot to order more in time so I got some Walmart brand ones (Equate) because they were still pretty cheap. They work the same way (with the lines), but they are pee sticks instead of dip sticks and they were easier to read. OPKs can get so expensive after a while, but they are at least cheaper than those ferning(?) things.
So in theory they can give you 48 hours warning that you're about to ovulate, but sometimes it's less. One time recently I actually ov'd on the same day as I got my +OPK. I don't think I knew that was even possible, but apparently testing every 24 hours, you can test just before your LH surge one night, then the next night catch the tail end of your surge, and then end up ovulating same day as your positive. So I don't think that's a typical scenario, but it wouldn't hurt to keep an eye on any other clues your body may give you.
My OPKs usually look faint for a couple of days, then turn "almost positive," then I get a true positive. I usually stop testing once I get my positive, but sometimes I'll keep going until it goes back to negative (next night or night after) if I wasn't completely sure how to read the results. So I try to start DTD at LEAST when I have my "almost positive," but sometimes we start a little sooner just in case. But then we run the risk of wearing ourselves out too soon.
It looks like your brand of tests simplifies that "almost positive" to "positive" thing but I'm not completely sure how to read it. I think once you do it a cycle or two though you'll think it's easy enough.
I usually get my +opk around day 13 and ov on day 15. Just on average. Of course your results may vary. Sorry I rambled so much. Good luck!
(why does that witch have to be smiley; it's like she's taunting me 
I changed yesterday to spotting instead of a light period day on my chart, at least for now. I was just so sure I was ramping up for full on bleeding, I was surprised when nothing else happened. I still think it was menstrual though because I think I saw little bits of endometrium.
I'm guessing the news from your GP is like a double edged sword . It's good that no on going issues were found but if " normal " then why ?? 
hope the news from your op is positive for you xxxxxx
