So I thought I started my period on Monday.. there was a light /brown when I wiped continuous till today.. my periods are normally so heavy by day 3 .. problem is there was nothing on my pad last night when I got up this moring and still nothing .. when I wipe tho it’s really light pink? Dose any one know why this is? I’ve had stomach cramps and feeling sick but not been sick.. any help would be great thanks! X
