Let me start by saying I am going to the doctor's on Friday.

That being said, I am on period #2 this month. What the heck?! I had one week on, one week off, and now my period has re-arrived. I am sure I am not the only one this has happened to. I was just wondering if any of you had had this happen and had any idea what caused it, or if it was just some weird fluke, or what. Again, I am going to the docs Friday. Just wanted some input from you lovely gals!

@_@ Hmm well I've had two periods in one month a few times before, but never with just one week between them. mostly 2 or 3 weeks between.
I really don't think it's anything you need to worry about, as our bodies are weird things sometimes ^_^

I don't know how old you are, but maybe you're getting to that "peri-menopausal" time of life? I'm at the age that it could be happening, but it isn't yet. I've just heard a lot about it.

The other thing is that when I increase my exercise, I almost always experience some kind of change. The last time this happened, I skipped one month, but then the next month was extra heavy and lasted forever.

Fun to be a woman sometimes, isn't it???!!

It happened to me 2 years ago while on 3 country international business trip. I am on birth control pills and due to time differences, jet lag whatever, I completely missed a pill without realizing it (in country days and my actual days of the week - according to the pill pack - completely got away from me). I had a period 2 weeks into my cycle (completely unexpected and awful, I was wearing light beige pants )

This happened to me once before. I had a provera induced AF and then started my period again two weeks later (thus, only about a week of non bleeding). I ended up pregnant that cycle (though, I was on clomid).

I don't know your age so it's hard to comment. I had started having periods three weeks apart earlier this year. When I mentioned it to my doctor he said I could probably look forward to menopause in another year or so. I would have thought there would be fewer periods, but that's not necessarily so. You are doing the right thing by seeing your doctor.

I'm 21. This has happened before, but I let it go and figured no biggie. And it's probably still no biggie, but now I have a bunch of girlies to ask, lol. I am also on birth control, recently switched to a different one than I was on before (about 3 months ago), and did miss a couple pills. Maybe that would alter it?

I have the opposite problem, my period comes sometimes every 2-3 or even 4 months.l am not on the pill,but agree with everyone else it might be the pill. I would talk to a doctor just to be sure everything is ok.

Depo caused it to happen to me several times.

Birth control caused me to do that once.

Screwing of on my Birth Control pills has caused me to do that a couple times.. I would say its probably no big deal, but you should definatly go see your doctor just to make sure! Can't be too careful about these things!

Missing a pill or two can not only mess with your cycle (my cycle is different by about two weeks on/off bc) it can also render the entire cycle's worth of bc useless. I have a cousin who got pregnant on the pill 4 times because she only missed one. I know you know all of this, but it's really important not to miss any pills if you don't want to get pregnant right now.
