Implantation bleeding?

Ra

So I’m 7-9 DPO (and we’re trying for baby #2) I tested this morning because I bought like a 20 pack of those cheap paper tests, anyway it was negative. Then this evening I went to the bathroom and wiped to find pink blood. I would say a medium amount.. and not red at all, PINK.

It’s not the color of my period. My period is also not due for another week. Could this be implantation bleeding? Is that a real thing? With our first baby I never had anything like this. She’s only a year old but my cycle has been pretty regular for the last 6 months so I don’t think my period is early. Anyone with a similar sitch?
