Could I just be a 50 year-old simply going through menopause with pregnancy symptoms? My tubes were tied, clipped and burnt 19 years ago. Now, I've missed 2 periods and recently had a brown flush of a discharge one day. I did the home pregnancy test and it showed not pregnant. I can't wait for my doctor appointment next week! My stomach appears as if I'm at least 3 months pregnant. Could I possibly be pregnant?
