Hello,
Menopause can occur in age 40-55 but premenopause is not the only cause of irregular and constant bleeding in periods.Other causes are there.
Excessive amount or duration of menstrual flow, at more or less regular intervals is called menorrhagia.Sometimes it is associated with polymenorrhea(Frequent flow, cycles of ≤21 days)Causes of menorrhagia are Hypothyroidism, Endometrial proliferation or hyperplasia like ovarian tumor and polycystic ovarian disease,endometrial polyps and neoplasia,endometriosis,fibroids and uterine sarcomas.
In my opinion you need to get your pelvic examination done from your gynecologist along with investigations like complete blood count,thyroid function tests,PAP smear and ultrasound uterus.Once cause of menorrhagia is identified,treatment can be planned.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Our cycles change all the time. They don't stay at the regular 28 or however many days they used to be.
You need to see a doctor. Could be something simple as a hormone imbalance or even a cyst or PCOS. A doctor will help determine this. Doesn't sound like early menopause, that would have other symptoms as well.
