I recently took 3 hpt the strip type test from clinical guard. However I do not get my menstural till the 17th of this month. I took 3 test and the lines are positive faint. But I don't know if its just the color the test turns to. There all came out same lightness. Should I wait till my missed period to see a doctor?

Yes. Most tests are not accurate until the day you miss your period. You may well get your period as normal!
