3 tests---soon to be 4!

So, I have had an ear infection for like 3 weeks and the ENT Specialist put me on some steroids to clear it up.  Before I start taking them, I decided to take a pregnancy test.  It came out positive, but not bright on the stick.  So an hour later I took another one, and it was like the same thing.  I decided to make an appointment to see if I can get a doctor test.  I go in about an hour.  I just took a 3rd test, and it's the same thing.  It's not a bright "+" sign, so I'm not sure and always skeptical.  Just about a week and half ago I was negative.  So never know!  So, on to my 4 test today!  WOWZER!  I'm keeping the tests to see what it says!
