for the past 6mo I have had a regular 25 day cycle with spotting for two days then heavy bleeding on the third In October I started spotting on the 17th in september I began spotting on the 10th this month I would have suppose to start spotting on the 4th However I spotted on the 6th Once on the 7th with menstration like cramps and back ache once today I should be heavily bleeding but there is only spotting when I insert tissue like the two previous days (Sorry TMI) with cramps and backaches and slight headache.....I lost 10lbs this month by cutting my sugar intake could that delay my period? or is it possible I'm pregnant(actively trying)
