My period normally comes every 28 days, give or take day. It only came a day and a half late, but I didn't even have half the discharge I normally do. Also, I normally have SEVERE cramps for the first 4-6 hours after my period starts and light cramps an hour before. I started getting light cramps about two weeks before I got my period, accompanied by bloating, an urge to pee more ofter (but not a UTI), constant headaches, and something completely new to me; very sore and tender breasts. I didn't get my severe cramps at all, and my period is astonishingly light... Should I be concerned?
