Implantion bleeding????

Is this what implantation bleeding looks like? Herr are some facts.... I should start my period in 4 days. I took a test a week ago due to having some cramping, nausea, sore breasts it was negative. Since then I am having minor leaking from breasts along with cramps, nausea and sore boobs. Then today noticed small amounts of this when I wipe. I didnt have bleeding with my first pregnancy. She is now 3 years old, just didny know what to be looking for. My periods are normally on time but I'm a very heavy bleeder. This is a first.
