Implantation bleeding


Has anyone experienced implantation bleeding? I have every sign of being pregnant but I started spotting yesterday and right off the bat it wasn’t a normal “spot or period”. By the end of the day it was almost completely gone and this morning it’s gone. I have one child and only been pregnant once in my life so I’m just really confused. My boobs are swollen and sore as shit. That’s how I knew I was pregnant with my daughter. Now I’m just confused.
