Reasons for Having a Period Every Two Weeks

~ 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 Anonymous,

How long is your normal menstrual cycle? How long did each period last? Was there a normal, heavy flow or spotting with each?

Consider speaking with your gynecologist, who knows you and your medical history. I can only suggest a hormonal issue, because the menstrual cycle is regulated by hormones.

Keep us updated,

Hello Anonymous,

It would not be so unusual if the first period was during the first days of the month, and the second started in the very last days of the month.

How long is your menstrual cycle? If the two periods were only a week or two apart, that would be a concern and something to discuss with your gynecologist.

Hi, I have a similar problem.
I'm 20 and for the last 6 or so months I've had two periods every month. They're either longer than usual and starting with brown-looking blood, or completely normal and going away within the normal for me duration. I'm a university student, so that adds up to the stress. I've had this happen to me once or twice before, last year, when I wasn't in sexual contact with anyone, so I'm ruling out an STD. My gynecologist gave me herbal pills a few months ago, but they don't really seem to be working, or they're doing their job very very slow. If anyone has any idea what could be causing that, please tell me, because it's freaking me out. Thank you in advance!

I am in my mid-30's and I appear to be having 4 periods every 3 months. It's still October and I am on my 13th Period of the year. Earlier this year I have had two cycles which were shorter than 21 days.

I am really worried about how this might effect me having children in the future as my partner wants to wait a few more years before we start our family. I am scared that this means I will miss out. No one seems to understand how important having children is to me or how worried I am about my periods.

There is no information anywhere about having 15 periods in one year and what it means. All I know is I find it really upsetting.

I will be 53 this year and I have been dealing with Menopause for almost 2 years now. I have my period every 2 weeks, sometimes sooner, and it lasts for 3 to 4 days and I use a box of 40 Super Plus Tampons every 2 weeks. I lose blood clots the size of a pingpong ball at least once or twice within the 3/4 days. I have always had heavy periods, however not every 2 weeks.
I am not married and never have been, however I am in a committed relationship and have been for the past 7 years and this BS makes it kinda hard to enjoy my sexual desires with my very patient and understanding Man.
"Aunt Flow" always comes to visit and I have NEVER invited her - can't stand the woman - she needs to be removed from Society!! lol
Just ranting and raving - I will deal with this part of life that God has bestowed on me, just like the rest of the "woman things" he seems to think we enjoy!!
Love to you all, Just Me

I found out I had an ovarian cyst last month (I don't know what size or kind). I went to the ER with pain in my right side thinking it was my appendix, but there was no infection in my blood. It turned out to be a cyst on my right ovary instead. I've never had children or been on any form of birth control (even though I'm 25), so it was my first pelvic exam and ultrasound. Fun times. Since then, I've had three periods every 2 weeks with stabbing pain so bad that I've actually cried into my pillow even after taking advil, etc. The ER referred me to an OBGYN and said that I could be seen once for free since I was without insurance at the moment. However, the specialist said it would be $185 for just an office visit. I can't do that. So, I made an appointment with my clinic even though they don't have a specialist like that there, and I have no idea if there's even anything they can do to help. If they aren't able to help me and this continues, should I try going back to the ER? Do you think they would just send me home to suffer? :c I feel stranded.
