Hi, Here lately my periods have been weird. For a couple months they were early. Then for a couple months they were late. Now they are really light. Last month my period was light too. I only used about 4 tampons. Now this month period has started again its also like last month. Last month i thought it could have been implantation ,but over the past month i have took 4 test all a week apart all negative with morning pee. I have not been sexually active at all this month so i know its not implantation this time. Whats going on with my periods?
