Premature menopause

I am 35 and have 4 children.  I had a tubal ligation at the
4th c-section birth.  Since then, my periods are always on time
20 days off 5 days on.  Always have been extremely heavy, always had to wear triple protection on 2-4 days changing 2 pads and a tampon every 2 hours.  The problem I am having is that the last 3 or 4 months my periods are either a week early or a week late, I have had 3 months of heart palpitations and I am cold during the day and sweat all night.  My mother had her
last period at age 46.  Is it possible that I may be entering a 10 year spell that will send me into menopause early?  I have had blood tests on everything except my hormones, they all came out fine. What do you suggest? And if this is the case, what can I do to make things more comfortable?  My mother went through hell and became an alcholic during this time.

I wish that I could help with input or advice, but I honestly don't have any.  I would suggest maybe doing a menopause search? I'm sorry I can't offer anymore than that! Good luck to you!
