OPK question

[JASMAK]

I don't temp, just use OPK's. I am trying to figure out how many DPO I am. If I had a peak on Friday and Saturday, but then it was negative Saturday night. Should I count Sunday as the day I ovulated, and then Monday as 1DPO, or do you think I shoudl count the Sunday as 1DPO, assuming that I O'd on the Saturday, the first day of a negative OPK???

It's hard to say because I always get a positive OPK the day after OV aswell, on it's way back down I presume. If you've never temped you wouldn't know how your LH levels tend to go...
Personally I would count saturday as OV day because it was negative again by saturday night.

Aha! Thanks! That was I was thinking...so that puts me 5 DPO.
