Bleeding?

How many of you have experienced implementation bleeding that lasts over 5 days?  What was it like did you have any red blood that was like your period. I've had 5 days brown spotting then had 3 days light but brght red and dark red flow. I normally have a 5 day period with 1 day spotting 3 days red and medium flow then a small amount of spotting.  Also had some spotting after sex 2 days after bleeding stopped that was bright red to start then went thick and dark brown
