Time of month...does anyone take special supplements to support temporary absence of this during competition training.  My doc wasn't concerned about it since she knows it's just for a season and said it will resume after.

Thanks

Never had them disappear on me at anytime!!

Mine disappear whenever I train more than a few days a week, and bodyfat around the 20% level. This generally isn't dangerous as long as it's only for a 'season'. When I was a distance runner I didn't menstruate for 5 years. I wasn't the classic underweight runner either, 5'4" weighing in at around 8st 2  -8st10 and 21% bf. Anyway got the chance to take part in some sports research where they found I was losing bone mass as a result of no periods - yup I was halfway to osteoporosis. So they then put me on the combined pill which brought them back. I've had to stop that pill now as I was having serious migraine attacks which put me at high risk of a stroke, and was making me feel pretty rubbish.
 
I've been told that high level athletes stop training for 6-8 weeks a year to have a couple of periods, that this is enough to keep your body healthy.  So if it's only for a few months you should have no problems, anything longer than that and it could cause problems. I take calcium supplements and of course weight training is recommended since it stimulates your bones.

Thanks GN, yes usually regular as clockwork, just since I've been training for competition since April/May.  

Think its probably down to BF being 13% mark, am 5.5 and weight is 9.12 mark, do weight bearing exercise and just started taking good quality calcium, magnesium supplement which also has vitamin C & malic acid (viridian)

Doc said should resume after competition training. She did mention red clover? 

Red clover has isoflavones which is why she may have suggested it, but I don't think there has been evidence showing that it will reduce chances of osteoporosis?  After your competition, they should resume and I don't think you should worry. It is for a relatively short amount of time and I know it happens to quite a few female competitors.
