Is It Normal To Feel Periods During Egg Transfer?

Hi. Im am on day 7 of Egg Transfer (ICSI) this is my first time and unsure what to experience. I have a 6 week cycle and today is my 6th week, I have all my classic symptoms of starting my period, which has obviously upsetting. Is this normal to have this feeling at Day 7 or should I expect to have my period? Thank you.
