bleeding again a week after period

Ok so i could use a little help please. Ok to start off ive been sexually active for the past two months with no birth control. Last sunday i got my period and it was 2 days late im usually very regular. And the first day my period was only there when i wiped i did not even have to use anything and then the next day it came. Which is different for me because usually my period starts off heavy. And that lasted for about 3-4 days and then stopped and now this morning i woke up with what seems like a regular period all over again except not as heavy as usual but its reddish brown and mostly comes when i use the bathroom but i do need to use a pad. Is this normal could someone please help me out id really appriciate it.
