Heavy Bleeding. Lipid, sugar are normal.

Since last few years i have a 22 to 25 day cycle and get my periods with regularity lasting for 4 to 5 days with moderate flow. Over the last few months the flow has reduced and length of cycle also is 3 to 4 days.In November i got my periods on 21st but it was just little spotting for a day and then nothing. On 3rd December which is day 13 of my cycle again got my periods. The first two days were light spotting but from third day am having heavy bleeding which i have never had earlier. Its lasted for last two days and today will be the third day if it continues. As am 43 and must be experiencing perimenopause, is this normal. How long do i need to wait for bleeding to stop before going to the gyneac. Am having no pain or any other discomfort except pain in calves and some fatigue. Have been taking Tab Angiwell 6.4 for last 5 months for some ECG changes along with Omega 3 and Evion LC. reports done 2 months back - sonography, lipid, sugar are normal.
