implant bleeding?

I just like to know a little more about it. Like how long it last? What kind of spotting? Like spots of blood or there is blood there just not whole pad. I just keep getting so many different stories from everyone. I spotted for 4 days. Had one small clot. And color was brown whole time. Know some people tell me yes it sounds like implant bleeding other say no. I bleed like a normal period week before I found out I was six weeks pregnant with my now almost 3 year old son. So I was thinking maybe that was implant bleeding. I had clots with him and look like period. Now this past week I bleed for four day first three days was only like hour a day last day was on and off all day. I know a test only thing tell me I am but did anyone else have any kind of implant bleeding so I can compare. Thank you
