Everybody is different but with me on ridgevidon it took my body around 2 months to get used to it and then I was on it for over a year and my ‘period’ came every Thursday night/Friday morning without fair
But then it started being Friday morning/Friday night
Then Saturday morning Saturday night then back to Thursdays
I think it’s just how you body adapts to it
If you have been on it a while you might not get the ‘period’ at all during taking it
