there is alot of info about ovulation in my journal.take a look..good luck to you.
thank alto i was realy scared.thanks
I guess you have a short LH surge. That's not uncommon. Do you OPK in the morning or pm? With such a short LH surge you may be better off testing in the afternoon.
Good luck to you this cycle!
Yeah, it's normal to get just one positive, followed by a negative the day after. The OPKs do not detect ovulation itself, but the hormone LH, which peaks about 24-48 hours before ovulation. So, the positive OPK combined with your 21-day blood test means you did in fact ovulate! Hope that helps :-)
