Hello. I got my first period 7 days before my 10th birthday. I am still a kid back then who loves to play with other kids and don't mind having my period so I don't really take notes of the date of my period. All I remember is that I often stained my uniform not knowing if its because of the heavy flow or just because of too much playing. I often get period twice a month every month during my high school years, it range from 5 to 7 days. I don't feel cramps of pain so i thought it was normal, but then Feb. 2017, I got my period for 14 straight days, it was so heavy and I was sent to hospital and had 3 bags of blood transfusion. The ultra sound result says it was due to hormonal imbalance and I had to take pills from then on. For more than 6 months I kept using the pills and my period became normal. it comes only once a month. So I decided to stop taking pills and for awhile, my period was still normal, until my internship came. Jan. 2018, I started having menstruation twice a month again, until today. I even started using an app and it seems like I my period comes every 15-16 days. Is it possible for me to get pregnant? I am single but I dream to be a mother someday, reading some articles about this makes me worry. Hope someone could answer my questions. Thank you!

I am 39 my last 2 cycles lasted 19 days and 12 day and am now on day 3 of cycle 3. I have been given every test under the sun biopsies,cervical cauterization and nothing has shown up or helped. I had my tubes tied about 9 years ago. Any ideas?

Hello Anon

You may be perimenopausal at age 39 - long and frequent periods are common for some women but you are bleeding a lot and probably need treatment. 

What did you have biopsied?  I assume the biopsy was done at the same time as the cauterization. 

Since you said you had every test, I assume your hormone levels were checked? 

We look forward to hearing back from you.

Hi Susan, I had a cervical biopsy and after that another biopsy from further up cant remember what that one was called. I had a whole range of bloods including hormones, iron, thyroid and blood counts. I also had ultrasounds. All tests came back normal. I have just been back to my gp as gyno referred me back to them after the tests. I am now going to try going back on contraceptive to try to regulate things otherwise she wants to send me for an endometrial cauterization. I asked if it could be start of menopause and she just brushed over that. I dont actually seem to have got any answers from either gp or gyno. Kinda frustrating as this has been going on for a few years now

Hello again Anon

It sounds like you've had a battery of tests but you are bleeding excessively, even for someone who may be in early menopause. I assume you tested negative for fibroids. 

Fibroids are benign (noncancerous) growths in the wall of the uterus. The uterus is the reproductive organ where a fetus grows. Fibroids often grow into the uterine cavity. In rare cases, they may protrude from the uterus toward nearby organs. Fibroids may be very small or may grow to eight or more inches in diameter. Usually more than one fibroid is present. About 20%-30% of women of childbearing age, and as many as half of all women, have fibroids. Many do not realize it. Most do not have symptoms until their late 30s or 40s. However, if all your scans and tests are normal, you may not be dealing with this. 

Contraceptives are for far more than birth control so it's a goo idea to try them to see if they regulate your system. If they don't work you may need to proceed with the cauterization. 

I can imagine how frustrating this is for you - please keep us posted as to how things progress.

Hi Susan I had a cervical biopsy and another biopsy to test for endo plus hormones blood counts iron and everything has come back normal. Just went back to the dr and asked for clarification from her and she said something about endometrial instability. I am going to try a contraceptive to get things back under control otherwise they are going to look at an endometrial cauterization.

36yo been having irregular periods for last 3yrs and last 2yrs i have my period twice a month sometimes 3 times a month. The flow varries from light to so heavy I feel like a fountain and have a lot of cleaning up to do! My last gyno appointment was in may or June my doctor doesn't seem to be concerned as my blood work and pap came back fine but since then they are getting more and more painful!

Hello Anon

It might be time to get more blood work done and to look for options like birth control pills that can control your cycle. Don't let a doctor fob you off by saying this isn't something to be worried about - she isn't going through what you are. Seek a different gynecologist who will listen.

Is it abnormal to get period twice a month? My very first period was when i was 11 y/o and now im 17 y/o. First time will be normal such that the colour would be red and the amount is average, however the second period would be brown and the amount is little. But both period are either 7 or 8 days. I'm quite worried

Sometimes, in very young women, periods can be irregular. Take the time to read the article and the answers already given. Consider calling to schedule an appointment with your gynecologist if you are still concerned.
