This is/was my first month doing OPK tests too.

I understand you have to do them at the same time everyday, not every second day. I'd re-read the instructions in the kit though.

I took a test every day from day 9 and occassionally got a very faint test line as apparently LH is always present but to get a positive result the test needs to detect a surge.

I got a surge on the evening of day 18 and I believe I ovulated on day 19 as I also had a temperature surge.

I found it hard to test at 2pm each day, so moved it to 6.30pm and got a positive. I did another test the following day (just to see what happened) and there was only a faint line, not a bold one, indicating my surge had passed.

That is why I think it is really important to do the test every day.

After the positive test result, O is supposed to take place between 12-36 hours later.

Hope this helps.

Nicole.
