Does the mini pill (nor-qd) help decrease cramps, make periods lighter and help reduce spotting?

It may or may not. You should have an exam with your obgyn, and you may be a candidate for one of the newer low dose pills like loloestrin which has only 10 mcg of estrogen and works very well for your symptoms assuming you do not have any problems with your uterus or problems like endometriosis which your doctor can evaluate you for, a newer medicine called Lysteda that is taken at period time can decrease bleedin.
