So update 11 DPO

I am now 11 DPO and after having a positive ovulation test and having sex twice that weekend I had bright red blood 7dpo (once in morning) and 8dpo (once in afternoon) which I never have. With 8dpo I came over all dizzy and hot and thought I was gonna be sick with some slight cramping then an hour later I was fine with no bleeding?!today I have had ever so slight spotting once when I woke up.what is going on?!?!?period not due for 5 days...!
