No LH surge??

Question

Every time I take an ovulation test,  it's negative.  No pink line at all-- not even faint.  I'm in my fertile window right now,  and I have all the right signs: EWCM, elevated temperature,  sore breasts, right ovary/ left ovary pain.  
I've had several positive ovulation tests in the past btw.
So, why do I not have an LH surge?

Answer

i agree with kerry, change your brand of test. ive just posted a pitcure of 2 different tests dipped in the same urine and one was a blazing positive and the other (which i was usin every day prior) was hardly even showing a 2nd line at all..

Answer

When are you taking the opk's? Best time of day to take them energy 11am and 6pm. If yourenot getting any faint line at all on them I would maybe change opk brand and see if it's maybe an issue with the particular tests you're using
