Ok, this is doing my head in so if anyone has any ideas then please fire away 
I'm charting and also using OPK sticks. On Friday I had a huge dip, and then on Saturday a significant temp rise, like, 36.68 to 37.09. But neg OPK.
Sunday, and today I have had positive OPKs and I suppose I have to believe those, because you can't have a surge AFTER ovulation, can you?
But what is going on with the temps? I don't understand. Today's was 37.07 so it's staying up. I'm baffled.
Can anyone shed any light at all? Thankyou x
