Pregnant or menopause with tubal

I do not usually start new posts but everything I have read does not answer my question.

I am 47 years old and I had by tubes cut and burnt close to 20 years ago.  In Dec 2012, my period did not come but in Jan 2013 I had a very light period that lasted 4 days.  I usually spot the first day then for 7 days the flow is very heavy then I would have 2 to 3 days of spotting.  After my very light period in Jan I started spotting 2 days later and spotted for 3 weeks.  The spotting went from very spotty to a little heavier spotting to spotty spotting.  In Feb and March the same thing.  I am due again the first week of April.

I am wondering if I am going through menopause but everyone I have talked to and everything I have read said that spotting all month is not normal for menopause.

I do not know if I am pregnant or not because the tests I took in Dec were neg.  I never had pregnancy symptoms with my first 2 children other than a missed period.
