Can implantation bleeding from pregnancy last four days?

Yes it can, but only slight brown spotting.

everyone's different mine was pink blood but some people think every one Implantation blood has to be the same as there's which annoys me from the person at the top. Implantation bleeding can last few days I did some research it said 1-3 days but maybe 4 for you ok Hope I help by the way everyone's Implantation bleeding is different some are brown/pink/red or thick/stringy even some can be spotting or blood in discharge so just ignore those people who say what there's look like every women is different ok
