Was wondering if you could help me out. I have a 28-30cycle but my period came early day 25 and the 2nd day was heavy, then the rest of the days were some what light, my period always lasts 5 days.this time it lasted for 3 1/2 days. Which never happens. Now since my period ive been so light headed, have dizzy spells (almost fainted getting out of shower) metal/blood like taste in mouth, and slight cramping. Also, urinating a bit more than usual. My boobs do not hurt, and have a bit of a.sensitivity to smells... what does this mean? Could i be pregnant... weight is still the same..
