Yes, stay on it. For years i went undiagnosed. Oh, it's in your head, it's normal, etc, etc. Till I was finally diagnosed a decade later and unable to have children.

I've had my period every 2 weeks for as long as I can remember. It started at 11, I am now almost 16. Is there any way I can stop it and get it back to normal?

I couldn't find a similar problem like mine
While my period comes once every 17 days and lasts for nearly other 17 days and it's happening this way since I was 21 and now I'm 25 and still this way
I went to a doctor two years ago who told me it's normal to have a long period with short time in between two periods
But I don't think it's normal since my period has never regulated
When I first had my period I was 12 and since then it didn't happen to be regulated
In the first two years I have it once every 24 - 27- 30 days and lasts for 6-7
After that I started to have it once every every 17 - 20 days and lasts for 10 days then by the age of 21 it happened to be messed up when I have it every 17 - 15 days and lasts for 15-17 days
Can you help me? Is it really normal as the doctor said or I should see another one?

This is my third period I over the last month in a half. I have blood clots and it seems to keep coming every 11 days. Normally I have a period 1 every three weeks or 20 days so I'm use to it being some what abnormal. I'm 35 years not on birth control I know I don't have a STD, am I premenopausal? At my age? Thank you in advance for any advice.

I'm 13 and I started my period (or platypus as i call it) 2 years ago and ever since then i've been getting dizzy, throwing up, terrible period pains, Diaherrea and two periods a month usually beginning and middle of the month as of this i dont think its my inhaler or my nightly tablets to help so i dont really know, I'm also not sure if its hormone imbalance (thats what my mums friend said) but i just wanted to know if there was anything that could balance this or make it so they arent as bad or do i just wait?

I was hoping some of you who have had this problem (period every two weeks) for more than 1-2 periods would post your outcomes. I have been getting my period roughly every two weeks and I can't get to a doctor yet. I just moved to a new city and don't have a job, thus insurance, yet. I'm 41 years old and I'm a little worried since I've had such normal periods all my life. Am I just premenopausal? What have all of your experiences been? Did things normalize or was there some medical issue that needed to be addressed?

Hello Anonymous,

I could not find any credible information to support the link between primrose capsules and the menstrual cycle. Some claim this herbal supplement helps relieve PMS.

But, it does seem to have caused changes in your menstrual cycle. Consider discussing this with your gynecologist.

Hello Anonymous,

Did you read this article? Do any of the mentioned reasons apply to you?

With such limited information, I cannot tell you why you got a period three times in one month. Consider speaking with your gynecologist.
