LH Surge? For a whole week?


I used and ovulation test on Monday and gave me a positive for LH surge. Tested Tuesday and received no surge. Tested Wednesday, Thursday and today and have had the same result everyday that looks positive. What is going on? Can you have a surge, lose it, then get it again for four days? Is this not positive? It's my first time using ovulation kits and I'm very confused. Here is a photo of the same result I got Monday, Wednesday, Thursday and today.
