I have been on Merina for about seven months, I have always had normal regual periods. Until this month, I did not have a period, I took two tests and both were negative, I did have lots of pregnancy signs ( been there twice I know the signs well). Now two weeks later I still feel off and I have very light, brown bleeding, almost spotting, there when I wipe and pee but not really anything on pantie liner, should I re-take a hpt? Is this normal for merina?
