Ok so I took 3 opks the first was 6dpo it showed up almost as dark as the control line. The next day (7dpo) it showed up almost non existent. Then I took another today (10dpo) and it showed up as dark as the first one I talked about almost as dark as the control line. My expected period (according to the app) is in 4 days. I know some of you will say you will always get a line I know these all were considered negative but watching how one day it was very close to being positive and watched it drop to very faint then 3 days after the very faint it showed up almost positive again in not sure what to think.
