Last night I got a positive OPK around 9:30PM.. woohhoo.. But out of curiosity, I took one this morning maybe around 7:30ish and it was negative. Should it have still been positive? It was only 10 hours or so later than my positive result. This is my 1st time using these so i'm not certain how they work.
