someone please put my mind to ease.

So everything is so weirdly happening to me waiting on a call back from Doctor. 
So I had sex 13th of October after a positive ovulation test
No symptoms some cramping ect, then my period shows up nearly 7 days early?? So am like what the France just go with the "flow". First day was pink spotting not noticeable at-all, second day we bit heavier we bit red but nothing like a usually have. 3rd day it was gone it was just old brown blood coming out. 
So that was what I thought was my "period" then again today a started spotting tiny tiny amounts hardly noticeable. 
What's going on??? Someone help🙄
