Implantation bleeding?

Sam
Ive had IB for six days now (apparently I take after my mother in the pregnancy department) And I've wondered to anyone else who has experienced this if when they wipe sometimes it's brown and sometimes it's pinkish/red, going back and forth a couple times a day? 
Another thing, did you have nausea a lot during early pregnancy? It seems like I'm constantly nauseous. 
Thanks!
