I would appreciate any help I can get on this one! Usually my charts are pretty straight forward.

According to my OPKs I really think I O'd on CD15 (Sunday) but FF gave me CH for CD 12! That is way early for me and it was before my positive OPKs. I did have a small temp rise but not at the normal post-O level that they usually are. My temp has gone up the last two days but FF won't move my CH...even if I cheat and put higher temps for a few more days. I know we are covered with BDing either way...actually better if FF is right but I don't think it is. Should I override to CD 15. Do you think that is right? I also have no clue where to put the coverline!

OR...Is it possible to O before your LH surge????? Do you think FF is right??? I did have more CM around the time it says I O'd...

I think I would wait a few more days and see what happens, but honestly, the temperature rise between CD 12 and 13 really looks like it was 12. Another few days and FF might change the CH though.

Production of estrogen from the dominant follicle peaks one or two days before ovulation. That surge in estrogen causes the anterior pituitary gland to secret luteinizing hormone (LH). LH is the hormone monitored by the OPK. LH travels through the bloodstream to the ovary causing enzymes to be released from the ovary which makes a hole in the sac of the dominant follicle. The ovum pops out of the hole and viola, you have ovulated. The LH surge makes ovulation happen, and occurs 12-24 hours before you ovulate. LH begins to rise, but does not surge, two or two and a half days before you ovulate.

That being said, the straightforward answer to your question as I understand it, is no, you cannot O before your LH surge.

The question on hand though, is the validity of your OPK tests. What time of day did you take them? Are you confident you recorded only the surge as a +? Since you started using the OPK before the LH surge (around CD10 or 11, assuming O on CD12), you should have been able to detect a slowly increasing level of LH (the test line was getting darker on your OPK).

It looks like day 12 to me.

I am having the same issues right now. I also posted about mine.

I prefer to rely on my OPKs and not temps. There are so many factors that play into temping i.e. did you sleep with more clothes, blankets, the temp in the room, did you toss and turn alot, etc. I think OPKs are more straight forward. JMO, everyone has their preference.

Ideally, to really really really catch it... You could use OPKs (to know beforehand), temps (to know after) AND checking CM (to also know beforehand). With any way of testing or checking, it's a matter of knowing your body and keeping conditions as similar as possible. Just like in a science lab where they test cool new things, the more variables or differences between the conditions, the more likely the test is to be not quite as accurate. That doesn't mean it's wrong, just means it might be a wee bit off.

Good luck!

It really does look like CD12 to me, but I think another few days of temps will make it clearer!

Thanks girls...It is just so weird because all signs point to CD 12 but the OPKs. I did them all around noon each day and the line got increasingly darker. There was no question on the negative ones and the positive ones. I guess the next few days of temps might change things.
