Tests like this for 5 days. What's going on?

[possiblyp18]

I have had OPKs like this where the result line is darker than the control for 5 days straight. 2 tests a day. I took a CB + yesterday and there was a very very faint line. I then done a FRER very faint line. Took another one this morning, same thing but even lighter.This is today's OPK has anyone else had this?

I did - it was my first clue that I was pregnant, I kept getting positive OPKs even though I was sure I had already ovulated, so I tested and got my bfp GL!

I had 7 days of dark opks then took an frer and got an instant dark line, what dpo are you?
