last cycle I was tracking I never got a positive opk and I wound up never really getting a period. I had spotting for week a day off heavy bleeding and it was over. I started to get a lot of cm so I tested with an opk because I was curious. It was positive. I tested the next day because I was positive. I was still really confused and so I tested on last time today and the test is still positive. can someone help me understand how it's positive?
