could just be a fluke or it might just be late. I have had that happen occassionally. 15 hours a week of training would not likely be the reason to cause a missed/late period. Usually, body fat, or lack thereof could indicate regular loss of your period.

Are you on the pill?

*edited....I only ask this because sometimes the type of pill you are on will interfere. I take Yaz and for a long while - it was hit or miss on whether I would have a period or not. I would have all the "fun" symptoms but nothing else. I did the same, bought pregnancy tests, called the gyno and they said sometimes it just happens especially with they type of pill I have.

Body weight, stress and peri-menopause are the three things that come to mind. Sounds like you don't believe yourself to be underweight. How old are you? I hit 40 this past year and I see slight variations that my doc chalks up to pre, pre, pre menopause. Oh really? There's more fun to come?

Stress is a huge one. Especially if you are stressed about getting your period on race day and you are thinking about it alot. Stuff like, "oh, I need to get my period before the 12 this month so I will be on schedule to be done with it by the 17th of next month for my race." That, right there, will mess with your cycle. Either way, if you don't get it soon, go see your gyn.

Women's bodies are so fickle. I wouldn't worry to much about it because really, why stress. If you know you aren't pregnate and if you hadn't had any abnormal paps and you are still getting your other symptoms and you aren't having any other problems generally I'd say you are ok. Just chalk it up to stress and training. If yours are anything like mine when they skip - look out! They sure make up for it! If it goes another 4 weeks... I'd give the gyno a call just in case.

I agree with the ladies, I'd check in with your doc just to be on the safe side.
If it makes you feel better I'm kind of in the same boat, and I've been sailing in this boat for the last 2 years or so. I'm on the pill and should have regular periods but I don't. When it does come, it lasts for a day, two would be maxing it. My gyno has checked me inside and out and everything has come back normal. She contributes it to the high amount of training.

REALLY? I tried one of those (or something like it) years ago, and didn't have luck. It looks like you have to "get it right" for it to work, so maybe that was my problem.
I too have messed with bc , but usually so my race is not the weekend before because I find my performance is WAY under par then. I do a Sunday start so if it's the immediate Sunday, no problem, but the week before ---BAD! funy. I will look into that again though.

Hmmm ok, well I will order it. It still says change after 12 hours so can you fudge with that? As in if you are doing an IM and are not so fast---getting there 2 hours before, getting your crap after the race..........don't want to be worrying about changing but I am light anyway... usually.

And I would say +1 to that ...having gone throug the same thing.....we stopped trying as of my 40th bd last month. Although after fertility drugs I now need to drop 20 pounds :( so not exactly low body weight...aahhahahahahaah

You know it is what it is. We could "go further" with the whole thing, but I just sort of want to mentally move on. It's way too stressful and disappointing. And yes, have thought about adopting...mixed on that. I would probably want to go international, and China for example has a 3 yr wait now. And because of hubbys age we would get an older child...We looked into adopting from fostercare but they make it so seriously difficult, so will probably just stick to Tri's and travel. I will probably go back to work or find some more volunteering to do. It's all good. I am just mad all I have to show for it is a flabalanch! ahahhaahahah

Yeah, you know from years ago on SNL--Dana Carvey

Britt I have definitely gone longer... there is no toxic shock issue like with tampons. I tend to rinse the Diva Cup when getting ready for work in the am, and then again as I get ready for bed at night. I don't even notice it the rest of the time. I guess if you have a heavy flow and fill the cup, that would be a different issue, but I've never had that problem.

And thanks for the heads up Toni!
