I use the clear blue advanced digital ovulation test. I had flashing high fertility Saturday and Sunday, then got my peak ovulation on Monday. I know everyone says to stop testing after the peak but I'm a pee on a stick addict and like to know my cycle 100% so I took one again on Wednesday and yesterday and received the low fertility. Then just took one this morning and it was flashing high fertility again. This has happened to me once before. Any ideas on why it may be showing up as high fertility again or what may possibly cause my body to have another lh surge?? 

Thanks in advance!!
