Bfp then bfp

Me
I had a super faint positive today. Af was due. However upon going over data I'm sure I ovulated late and on the 2nd. Well I took a test this pm and it was negative. Like start white. I also had a super faint the day before. I just don't get it.  I go to the dr tomorrow for an ankle issue and might ask for labs. Will it even show on labs yet?
