Suggest Remedy For Delayed Periods

I'M 8 DAYS POST IUI AND IF FEEL LIKE MY PERIOD CAME TODAY. STARTED OUT LIGHT PINK FAINT NOW IF HEAVIER. IF DID RECEIVE 10,000U OF HCG 36 HRS BEFORE MY IUI. MY PERIOD USUALLY COMES EVERY 21-26 DAYS. AVERAGE IS AROUND 25 DAYS. SO THIS IS WHEN MY PERIOD WOULD COME. IS THIS TOO EARLY POST IUI FOR MY PERIOD?
