So periods for me have always be extremely painful & med-heavy flo since I have had them. I was 2 days late, 1st day I took a Sainsbury's pregnancy test, it looked like positive but it was too faint to be a positive looked more like an evap line. I did not take another, I was gonna wait a few more days. Then I get my period, It's not it's usual Med-Heavy flo and the cramping was not my usual, the blood is usually quite red but this time it's more pink and a very light flo. Skip a few days and I notice there was not blood on my 2nd day of 'AF' then it was bleeding again on the 3rd day I noticed there was no blood again in the morning when I went to pee so I took another test (also came back negative) then there was that pause later in the evening. I'm really confused with myself 
Do I wait for a week and take another test? & use a different brand?
