Need help

My last period was August 7-11th now today September 5th I started spotting blood and a few clots .. I was told to take clomid soon as I start my next cycle but for some reason this seem like an early period my cycle was never every 28day so should I consider this a period or no .. should I still take the clomid on cycle day 5? Also I been having a lot of sex almost everyday from August 18th- til now so what should I do or what can this spotting me cud it be a start of a period even though it is light
