Birth Control....

I’m not new to the pill. I was on it for three years and am back on it now as I just got married (became sexually active again). Never had issues before. I’m in my placebo days and it’s been awful. Started spotting four days before my placebos. Been feeling just sick. Cramping so much and yet, hardly any blood. I’m a HEAVY bleeder usually so when I feel the cramps I’m thinking, “here comes the flood” and what is it? Barley anything. I’m usually through super tampons every two hours and instead I’m using one regular for the entire day! I am tired of the constant weak, nauseous feeling... anyone have this with birth control? What helped?
