My period came two days early and its now day four it started just spotting which was light pink but then turned brown but picked up a still not enough to fill a pad and is still light pink and today it went back to just spotting light pink unless I pee when I wipe there is a bit more than spotting but its light pink. No clots, and I only got cramps for about 30 minutes the day I started and haven't had any since. Im having a lot of pregnancy symptoms, tiredness, back ach, soreness, legs and feet hurt, nausea, head ach, anxiousness, constipation, and my veins are visible veins all over my body, and on the side of my hand one is protruding, and I've been eating a lot more sweet stuff than normal. Could I be pregnant?
