I got a positive opk this morning - after only holding urine for an hour and it was my second pee of the day. I'm assuming my lh surge actually started last night for it to be SO positive this morning. I'm trying to figure out when I'll ovulate. I'm going to keep testing a few times throughout the day to see if it stays positive. My question is- will it be negstive if I'm ovulating or can you still get a positive opk DURING ovulation?
