I had my last period on November 22nd. I spotted just when wiping and it was light pink on December 3rd and that lasted two or three days. I had nothing until last Friday 1/7/11 and it is very light and pink again. Now I have a very regular and very heavy cycle and the latest I have ever been us 31 days. I am 34 if that matters and have been unable to conceive, no birth control in about 8 years. I have taken several hpts all negative and even had a negative blood pregnancy test. I am scheduled to go to the doctor on February 1 but its driving me crazy so thought I would ask and see if this has happened to others and what the cause was

Thanks
