I had mytubes cut last December and have had normal 3-4 day periods since however I had a nomal period kind of light but mostly normal this month and finishe about a week and a half ago... today have started spotting light red,pink and brown spotting ih abdominal and lower back cramps? I have had unprotcted sex but didn't think it was a worry since I had a tubal ligation last year? Any suggestns or ideas at all would help... thanks
