Positive ovulation test 2 days in a row...???

Candice • I have an amazing 4yr old daughter, who was a rainbow baby! We are now expecting a rainbow baby, another princess!
Is it possible to get a positive ovulation test 2 days in a row? I thought yesterday was my peak day, the darkest line I had seen. But then I tested again this morning and got this... I'm new to OPK, so I'm still trying to figure out how it all works. Could my peak day be today as well? I read the LH surge can be anywhere between 12 and 36 hours. Would that make me test positive for 2 days?
