When an ovulation test goes - after a +, does that mean ovulation has occurred?

Answer

Well, an OPK detects an LH surge which generally takes place 12-36 hours before ovulation. I would combine OPK with checking BBT as well, and this will give you a better chance of knowing if you actually ovulate! Just because you have an LH surge doesn’t always mean you ovulate. It could mean your body attempted ovulation and it may have been unsuccessful. Sometimes we have “system glitches” as I like to call it..So to answer your question-Not always!
