I just bought some IC's for the first time, and only started OPK's last month. Last month I used dollar store cheapies and the pattern was like this:
CD 14 - no line
CD 15 - faint line
CD 17 - neg at 10:30, pos at 2:30, neg at 11:30pm
CD 18 - O (temp spike)
This month with the IC's (of course I had to try them as soon as they arrived )
CD 9 - no line
CD 11 - faint line
Oh, and both months, I had EWCM on day 11 that then disappeared again until O.
So my question, after all this preamble...
In your experience, are IC's more sensitive than DS cheapies? And if not, do you think I'm going to O in the next few days (because of course, you are psychic and know these things!)? Last cycle was the earliest I've ever O'd but I just weaned DS last month so maybe my cycles are changing like crazy? Or maybe I'm the crazy one.
Thanks for listening.
I'm not sure of the sensitivity of the IC vs DS cheapies, but I believe that for either, once you get your final positive OPK, you can ovulate anywhere from 12-48 hours after. It's also best to use OPKs mid-afternoon instead of in the morning.
I always get lines on ICs and they are very positive when they are positive. I used a Wal-Mart brand this last cycle because I was out and not planning on using them at all but the OB asked me to test, and the lines on those were not as dark during non-ovulation time, so I do think the ICs are pretty sensitive
FOr OPK's if the line is anything BUT as dark as the control line, it's neg. The hormone it detects is always in your system, so to have a faint line entirely through your cycle could be normal/possible. I would try not to put too much thought into a faint line.
I think definitely if you just weaned your hormones might still be trying to sort themselves out. Your best bet would probably be to monitor your cervix and your CM as best you can and just be on the look out for that truly POS OPK.
I think they are more sensitive than others. I get "almost" positives a lot. Then again, could be my hormones.
