PERIOD TABLETS!!!

Hi everyone am just wondering I have a doctor calling me tomorrow to talk about my periods not coming back due to having implanon out 4 weed ago I know it's takes a few cycles for them to come back but I'm wanting them back as soon as I've took tests and they say negative I've also read up about getting pills to help get periods back! They were irregular on implanon! Has anyone had tablets before and they have worked ??
