i am 6+1 today and every test i have taken before today (approx 8) has gotten very very dark very quickly. Well I took one this evening, same brand, and it was very light pink. Compared to the DARK red they have been...Even after 10 minutes it was still pinkish and not too dark. Ive been using the same brand each time, and I hadn't urinated in 9 hours or so. Other tests I have taken that were dark had been on my 5th urine of the day, even only 20 minutes after using the bathroom. Should I be worried??? Does this mean my HCG is dropping?!?
