My periods have always been a normal 5 day period until this month I was a whole 4 days late and then I bleed for three days with no clotting. BUt by the third day it was just brown spotting and that was it.. I mean I know me and my husband did our thing right before my period but could that mean I'm pregnant and cannot tell yet? I'm tired and been felling alittle under the weather lately but I dont want to contribute it to being pregnant. Any help here?
