Hi there, This is Dr Basu, Experienced Specialist. I am here to address your concerns and provide great service.
You do need some proper evaluation.
Irregular heavy periods can be caused by the thyroid gland disorder.
Thyroid gland also can cause palpitations.
Hence, serum TSH and free T4 levels should be checked.
Also you will need a holter monitoring 24 hour at least to look for any atrial fibrillation or any other irregular heart rhythms.
the irregular period can sometimes be related to the uterus lining thickening.
this can be sometimes precancerous known as endometrial hyperplasia.
Hence, a pelvic ultrasound is required to check for uterus lining thickness and also presence of any tumors.
Anemia can be related to your heavy periods.
Still vitamin B12 and folate deficiency should be checked which can also cause anemia.
Please ask for these tests from your GP or consult with a gynecologist.

I clicked the Excellent face straight away yesterday as I was happy with the speed of your response (although I was surprised at your thyroid suggestion and will follow up with my GP). I have no idea why it didn't register, but I am not happy having my inbox filled up with messages from you! I will now simply rate 'Good'.
