Implantation bleeding

Aislinn

I really think I’m having implantation bleeding. My cycle is pretty regular and I never have a light period. This time I have pink discharge like a week before my period is due and I have had it for 4 days. No spotting but pink discharge mixed with old blood. Last time I had this I was pregnant with my son who is now 16 mo. I feel pregnant but keep getting negative tests.
