Reasons for Having a Period Every Two Weeks

Menstrual Cycle related image Andres Rodriguez/PhotoSpin

The menstrual cycle occurs in all females from the onset to puberty (average age 11 or 12 years) to the menopause in middle age (average age between 45-55). The lining of the uterus is shed via vaginal bleeding when a girl or woman has not conceived a pregnancy.

The menstrual period lasts between two days and seven days, usually occurring once every 28 days, although anything from once every 24 days to once every 35 days is considered normal.

If you are having a period more than once every 24 days, it is considered an irregular cycle.

Having a period once every two weeks, or twice a month is abnormal and you should see your doctor because you may become anemic if you are having very frequent periods. They are sometimes a sign of infection or other medical problem that would need treatment.

Reasons for a period every two weeks could be:

• Dramatic weight loss or gain -- This changes the hormones in the body and these are responsible for directing when the period will start.

• Excessive exercise -- This too disrupts hormones.

• Stress -- Exams, family argument, financial worries, divorce, even a holiday can cause a temporary change in your menstrual cycle.

• Illness and/or medications -- Some medications can affect your cycle. Talk to your doctor about altering or stopping your medication if you think this is happening.

• Uterine problems such as polyps, cysts, fibroids or tumors (either benign or cancerous).

• Sexually transmitted infections -- These can cause bleeding in between periods which can be mistaken for a period.

• Thyroid problems -- Thyroid disease could cause a thickening of the uterine lining, resulting in more bleeding than normal.

• Reactions to contraceptive methods -- Sometimes the pill, depo provera injections or the copper-only IUD can result in a change in your cycle.

~ The pill and IUD can make you bleed in between periods, known as "breakthrough bleeding" and this may be mistaken for a period.

~ The IUD can also make your periods heavier.

~ The depo-provera injection can make your cycle irregular, however, it often stops your period altogether instead of making it more frequent.

I have normal periods, Although this year my period has been slightly irregular. Starting in June of this year, i noticed that I was spotting two weeks after my period. Then after spotting for 4 days, I got my period again two weeks later. Then in early July, I was Spotting again on the 7th, then my period on the 30th. August, September, and October were regular periods a month apart. November which was last month I spotted a little and got my period at the end of the month. And right after that period, I was off for about a week then more Spotting, and the following week , which is now, I have my period again! Idk what's going on with my body. I've never had irregular periods and have never spotted this much. I just turned 27 and I'm only sexually active with my boyfriend of 8 years. I havent had a dramatic change in my weight and am positive it's not an std or sti. I'm thinking I may go to urgent care and get referred to a specialist. I made an appointment to see my doctor and nothing is open until January.. I don't want to wait that long. Please help!

Hello Anonymous,

January is only weeks away, and you have been experiencing this since June. You could visit an urgent care center, but honestly this will not be looked upon as urgent.

I'm 26 and right now my husband and I are working on kid number two. Yesterday my ovulation test came back positive, fourteen days in, and today it seems like I'm suddenly having my period. Of course the pregnancy test today came back negative, like the last few I've taken sadly, and I don't believe I'll be able to get any accurate results for another few weeks. I've had months with double periods only a few times before so is it just a horrible coincidence that I've having one again, if it's even possible after testing positive for ovulation. Or is it more likely something might be wrong? As of right now my doctor's only advice is to wait a little longer but I'm scared and hopeful it might have something to do with getting pregnant.

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,
Maryann

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.

Maryann

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!
