Your LH surges anywhere from 12-48 hrs before you ovulate with the average being 36 hrs, and a normal surge can last 12-24+ hrs so most of the time your OPKs are negative before you ovulate. That being said, you can have a pos OPK in the morning and O that night. Or you can have a pos OPK and then O 48 hrs later. That is why they tell you to start BDing when you get your pos and keep BDing for the next 2-3 days. Also, a pos OPK does not mean that you will O, it only means that your body is trying to O. You may have several pos OPKs in a cycle and you can have a pos OPK and not ovulate. That is why most people also charge their temperatures. If they get a temperature increase 12-48 hours after a pos OPK, then they are pretty certain that they O'd, if not they know to keep doing the OPKs incase their body tries to O again later.

This month I got my first pos OPK in cd15 around 12 noon and it was as dark as the control line. On CD16 I tested 3x and the test line was about 3x darker then the control line. On cd17 at 12 the OPK was still as positive as the control line and was neg by 9pm that night. So basically I caught my surge going up on CD15, at its peak on cd16, and going down in cd17 and it lasted about 48 hours. This is not normal for me. I normally have just one positive and then ovulate the next day. My charts are saying that I O'd on CD17, but I didn't get a large temp spike until cd18..

I hope this was helpful,

I'm feeling kind of like I'm rambling today
