Sounds like your ovulating either for the first time (maybe your body geared up to O but didn't) or again. OPKs can be use as pregnancy tests but by the time you get a positive OPK you could get a positive HPT because OPKS arent very sensitive. I would be bedding just incase, and expect AF may be a little later then you expected!

Additionally, OPK's are not as sensitive as a lot of HPT's are. This means that, if pregnant, you are likely to get a positive HPT earlier than you would get a positive OPK.

Elaboration: a lot of women e-mailed me expressing surprise at this. Keep in mind that HPT's are oftenmore sensitive than advertised. First Response Early Result was found, in one recent clinical trial, to detect consistently as low as 12.5 mIU/mL of hCG, and sometimes as low as 4.5! OPK's are never more sensitive than advertised (they are detecting a hormone "surge"; if they are too sensitive they will turn positive from the normal all-the-time presence of LH in the female body.) The most sensitive OPK's on the market are 20 mIU, and some are sensitive to 30 or 40 mIU. OPK's may have a second line in the presence of less hormone-- the sensitivity refers to the threshold at which it turns positive.

So, if you are comparing a sensitive (20 mIU) OPK to some less-sensitive HPT's (sensitive to 25-50 mIU) then yes, it's true an OPK may turn positive before an HPT. However, the most sensitive HPT's available are more sensitive than the most sensitive OPK's available.

Most importantly, OPK's are not purified as well as HPT's are. Therefore, they are more prone to "errors" and positives do not always mean that either LH or hCG was detected. In other words . . . they're simply cheaper, shoddier tests.
