Hey guys so I am on a period tracker app for months and it is pretty accurate only out by a day or so and it said my period was due on the 9th of December but for the past week and a bit I've been having cramps, headaches, nausea, fatigue,sore nipples,creamy discharge so I've taken a few pregnancy tests just to be sure and saw nothing granted I was testing too soon as date of possible conception was around from 22nd to 25th November all high and highest fertility windows according to my flo app I was late for my period by 3 days and then today I got what I thought was my period but normally my periods are super heavy going through 2 tampons an hour cramps that make it so I can't stand up straight but the period I have right now there's little to no cramps the flow is super light the colour is pinkish and brown I'm not sure if it could be implantation bleeding as I've never had any symptoms leading upto any previous periods nor any this mild any advice would be super appreciated
