~ Sometimes changing or stopping your method of contraception can cause a sudden drop in hormones and this can result in a change to your cycle.

• Onset of menopause -- In women aged 45 and over, having periods every two weeks can be a sign that you are about to go through menopause. It can be a sign of ovulation beginning to shut down. If you are under 45, having irregular periods in addition to other symptoms commonly associated with menopause, may signal premature ovarian failure.


Sometimes treatment is not necessary, for instance, if the disruption in cycle is due to stress, weight loss or gain, or illness, it may be temporary and may correct itself in time.

However, to rule out other possibilities your doctor will perform a pelvic examination. Your doctor may also take a sample of the uterine lining as well as doing an ultrasound scan to see if there are any obstructions in the uterus, such as fibroids.

If any obstructions are found, you can be referred for surgery to have them removed. If any cancer is found, you will be referred to an oncologist who will plan your care with you.

Sexually transmitted infections can be treated with antibiotics (and the use of condoms to prevent further infections). Your partner may have to be treated as well.

If the problem is caused by a contraceptive device or medication, this can usually be changed to stop the problem.

Heavy and/or frequent periods can sometimes be controlled by certain brands of the pill. If you find they are really disrupting your life, for instance, you are bleeding through your clothes, have to miss work days and can’t plan your holidays, this may be an option depending on your medical history.

Hormone treatment could also be given in this scenario, if you have thyroid disease or if you are starting menopause.

Hello.. ^^
I can go by the name of Claudia.
I just want insights about my current situation.
I didn't have my period for the whole Month of May. It started on the first week of June and I was wondering why I keep bleeding over 14 days. After the second week, my bleeding reduced to small droplets in my pad which then lead to alternate days of having drops of blood in my pad or no drops at all.

I don't have a right ovary anymore. It was removed when I was 10 (Right now, I am 19 years old), because of ovariancyst. I'm going to see my doctor soon, but I just want to know about factors that could be affected. Does this mean, something's up with the ovary I have left? Would I still be able to get pregnant?

Hello Claudia,

The menstrual cycle is regulated by a precise balance of hormones, Your case is unique because you have only one ovary.

These are all good questions that can be answered by your physician during your upcoming appointment..Keep us updated.

Hello Anonymous,

It would be a very good idea to schedule an appointment with a gynecologist.

Hello Anonymous,

Three periods in one month is very abnormal and is putting you at risk for iron deficiency anemia. Please call your gynecologist today.

Hi, I m 23 years old with a 0 % chance of pregnancy. From june 2016 ,I m facing irregular periods. after june i got my periods in the first week of october 2016, in between periods i had a fever for which i took antibiotics and in novembr i travelled more than a routine,after that I had my periods in Feb 2017 .From feb I m having heavy periods of about 14 to 15 days . just after 10 to 12 days periods start again which lasts for that long again.. In between periods , i m having dark brown spotting.
I went to the Doctor in April .And she said its because of increased weight. but i haven't noticed any big change in weight .
My height is 5.1 and weight about 70 kg.
Should I go to another doctor or should just rely on loosing weight.??
