The pill

I started taking the pill on March 4 And my doctor said for me not to take my sugar pills which start my period for 3 months. So I'll hAve a period every three months. Since the country I've just felt a lot don't in that area and I have had cramps and I'm not supposed to take my sugar pills for a mother week or so. I'm not sure what's going on but I feel moody and emotional sometimes and honestly I don't know what's going on down there
