I have a dx of Probable Autoimmune Hepatitis, however it has never been bad enough to warrant any treatment to date. I havent had a Period since October 30th and there is no way I could be PG as I had a tubal done 16 years ago. I read online that sometimes AIH can cause you to miss a period when its in advanced stages,does anyone here have any light to shed on this subject? I am clearly wondering what is going on with me, given the fact I have not had a period since October. Any thoughts?
