After many years (started at 14 am I 20 now) I have suffered through what I now know is endometriosis, severe pains in my lower back, legs, and abdomen, vomiting, dizziness, and sometimes passing out due to pain. I have read reviews for Norethindrone pills and I'm not sure they are 100% for me. Combination pills are not likely either due to the fact I smoke. If someone could give me a little insight on these pills I'd greatly appreciate it.
