My period came on the time late in the afternoon, very light the whole day no cramping. Day 2 in the evening came down heavy, day 3 watery with blood clogs, day 4 watery, day 5 and 6 just pink when i wipe and some spotting. This has never happen b4, now my breast have been hurting b4 my period and are still hurting. I took a test b4 my period and it was negative, not sure what is happening. Could I be pregnant?
