Period after chemical...

How long after your chemical pregnancy did it take for AF to return to normal? 
I began to spot 7 days before my period was due in August. I took several positive pregnancy tests. 2 days after AF was due I began to bleed red blood. The DR confirmed  there was no pregnancy on Aug 17. I continued to spot until about Aug 20. I haven't had any spotting but also do not have signs of PMS (I usually get a headache, sore breasts etc.)
