I've been doing opk's for the past 5 days 4 times a day as I know from past experience that detecting my LH surge is hard. I've had two lines for the last 4 days with them getting darker but not positive. Yesterday I had o pains & then today my temp has spiked suggesting I ovulated (which would be on time for my cycle).
I did another opk this morning & it is darker & then just now & it's almost positive.
I am certain I've ovulated (pain & temp rise) so why are the opk's only now positive? Is the opk or temp more likely to be wrong?!
Photos of opk's (today's are the top 2). None are positive but chart & symptoms indicates already o'd.
