My menstrual cycle is all messed up now

Oh yes. I looked it up and couldnt find anything consistent that backs up changes in your TOM with weight loss but I was so worried I had an extra smear and a Gyn test at the docs. I was taking a pregnancy test every 2 weeks in July / August I was so worried. lol

First month weight loss: Period never came.
Second Month: Period Came 7 days late. Never.STOPPED!

I was spotting for 1.5 months. Since I'm on the 6 monthly smear list, I was really worried it could be cancer. I was also worried it could be pregnancy as spotting in early pregnancy is common.

Got the all clear. Had an internal check up with a female doctor, nothing wrong there, either.

Third month ( this month ) Period bang on time, but only lasted 2.5 days. Took a pregnancy test again, I'm not pregnant.

Being on the Pill ( Rigavidon ) means I should be VERY regular. After having been on it for 8 years I know exactly when my period will arrive and when it will end. I have never experienced any spotting or late periods before this new weight loss plan.


I LOVE my new body. But I have to admit the stress of thinking Im pregnant every month is getting to me. lol My Doctors have suggested going from the pill to the implant but I hear periods are much more irregular on that and I dont need the extra stress.

Sorry to say this girls but Im relieved Im not alone. We cant believe everything we read online but when I searched for weight loss and change in periods there was so LITTLE out there that I thought " Hmmm its just me then >_> " and have worried ever since.

I take fitness classes with a female doctor. She told me that anything as little as 10lbs lost can change your cycle.
Personally (no medical backing it - just what I've read on the oh-so-reliable interwebs), I've heard that under eating and/or being underweight can make your periods basically disappear.

Good idea to be heading to the GYN!

My period completely stopped. When your body changes, your hormones change too... thus changes in menstruation.

I am feeling you on this. I have changed drastically over the past few months, I just chalked it up to moving but now I'm thinking it's time to head to the doctor because definitely dont want to be thinking I'm knocked up every month lol.

Oh I know!

And I would have been happy with at least seeing some sort of period each month, but then you've got people telling you " Oh I had a period every month when I was pregnant! " etc and you think - does seeing your monthly friend even HELP you calm down? Even if its a HEAVY one I now worry! lol:

Checked my pill information pack:

"If your pill free week is lighter, heavier, earlier or later than usual, you could be pregnant. "

All of these have happened to me for the past 3 months. So I'm in a constant state of worry. haha

I'm also in the camp of getting it more often! It's the pits starting every 21 days! Glad I'm not alone in this and as others have said I've done searches on it and there really isn't any info on why this happens.

In the last 4 months I have gotten it twice...its like I get it every other month...spoke to my gyno on Monday she said it can happen like that on pill......never has before now.

Mine has always been very regular from onset at 13 up to now (age 36!)...but since losing the most recent 25 lb or so, I have noticed a pretty big change.

Before, I had days of back pain and light cramping before I started spotting. I spotted for 2 days and then bled moderately 2-4 days (with cramps) followed by 2 more days of spotting.

Now, I just have major breast sensitivity for 1-2 days, then my period begins with moderate bleeding for 2-3 days (with same level of cramps as before). Then it abruptly ends, or maybe 1 day I'll spot slightly.

I prefer it now. Although it would be fine with me if the cramps would go away, too ;-)

Hormones are stored in fat so when a woman loses fat, more hormones are surging around the body messing everything up. However, My doctor always told me that if I notice not having a period for more than 3 months go to the doctor. Also, if your period stays really off kilter even when not losing weight go to the doctor then too. Though it can just be hormone related based on losing fat, it can also mean worse things.

I have PCOS so my period has never been regular even when on birth control and when I started losing weight it got even worse!

I haven't had my period for 7 months and I've had all the tests; pregnancy, blood, ultrasounds, thyroid etc... Would love to hear some suggestions as to what to do next. I ate 1200 calories for like 5 months without eating exercise calories and I wonder if this might have caused some damage..

Not neeccessarily damage... But at such a reduced level of calories over a long time frame, it's possible your body just didn't have the energy to prepare for pregnancy, therefore, no periods. Women who don't eat enough, lose too much weight, and/or exercise too much often experience this. From what I've read, it's not permanent. Feed your body well and hopefully you're hormones will return to normal.

See! I knew there was a good reason to keep feeding my wife ice cream. I thought the taste was making her happier but it turns out that it's sucking up all the hormones and sedating her apparently. Anytime I get the suspicious notion that it's that time I buy buckets of ice cream. There will be no free-floating hormones at my house. No sir!

Good to double check with a doc, but changing your eating and exercise most definitely can affect your cycle.

Well... my experience isn't to weight loss. But my periods are usually heavy and painful, both at menstruation and ovulation, and recently, they are coming closer together (about 20 days apart). I have endometriosis and the doc suspects that I might also have PCOS. Be sure to have the doctor do some bloodwork and take a look at your hormones.

Unless you have a super low body fat percentage, odds are this isn't related to weight loss.

This thread has calmed me down so much more than any of you realise. ^^
