3 yrs ago I had an endometrial ablasion (roller ball) and it completely stopped my periods. My GYN told me this would make me sterile. Is this true? I divorced last year and began a new relationship (now serious relationship) back in May. We became sexually active about 5 weeks ago. My ex and I had not been active for a few years. Over the past week, I have had some mild uterine cramping, fatigue and nausea. We didn't use protection because I told him I couldn't get pregnant. Is it crazy to think that could have happened?
