I used them for several months. I would start them on day 12-13 and get a lighter line and as the days progressed, it would get darker and darker until I got a + on day 15 or 16. My cycle has been goofy for the last 2 months and last month I used up the whole box to day 18 and nothing happened. It turns out that I Oed late (like day 21). Anyway, I've been charting my bbt this month and I like it a lot better. For one thing, it's A LOT cheaper. I bought a fertility monitor (I haven't used yet) because I'm tired of spending all that cash on the OPK's. Good luck to you!
I'm just hoping that the last couple of tests aren't positives and just faint positives. I will test for 4 or 5 more days and see what happens. How, exactly does the fertility monitor work?
The monitor has you do a bunch of test sticks (you pee on them) all month and it learns your cycle. The second month, it asks you to test a lot less and can tell you when your fertile days are. It even tells you to expect AF.
No mistakes. I would even ask DH which one he thought was darker (once they get pretty dark you are pretty much set).
Oh, I also have found that it's easier just to BD every other day from day 10 to 25.
I had a light surge line the first day...day 18...cause I am on clomid..then bam! full dark line..if not darker than control line..........both days............definitely noticeable!
