That's not normal, but I would assume that it is a result of a bad test or poor testing and not your body. The reason I would assume this is the ovuation tests react to the presence of Lutenizing Hormone (LH) in the urine. LH is produced only when there is a sudden drop in Estrogen. The sudden drop of estrogen triggers a spike of LH. LH dissipates from they body within 24 hours; It leaves the body so quickly that it's easy to miss an LH surge if you test at 25 hour intervals.
In the 20 years I've has an active theriological practise, I've never seen susbsequent LH surges. I've seen LH surges separated by several days but only when artificial lutenziers were administered to trigger ovulation.
