I tested positive for lh surge on day 11 with 32 day cycle. i tested again 5 hours later and it was negative. multiple lh surges possible in 1 cycle?

Unusual: But, the lh surge is highly variable among women. It generally occurs over a 24 hour period. The level of lh can vary with the time of day when you take the test. If you are on the 'downside' of the lh peak, it is understandable that your second test was negative 5 hours later. Note, that ovulation generally occurs 12-36 hours after the lh surge.
