LH Surge
How long does the LH surge last? If I test every morning first thing, will I catch it or is it possible that I will miss it?

Dear bells

The LH surge lasts for less than 24 hrs. However, due to the significant level of Lh released into the circulation, the levels in the urine remain elevated for a somewhat longer period. Therefore the once daily urine testing, if done correctly, would be adequately sensitive to detect a normal LH mid cycle ovulation peak.
