xKimmi, what are your periods normally like (pre CD) and were you regular? There is no doubt that low carb and VLCDs interfere with some people's normal cycle and the effect seems to be worse for those on some form of contraception. However it would seem that for most people, this interference takes the form of more frequent/constant bleeding. This usually settles within 3 months or so. Interestingly, CD seems to affect periods more than LLife does, this does not make any logical sense to me as a health professional as the pack nutritional make-up seem very similar. It could just be that the CD forum on here gets more posters than the LL forum.
It would be logical to check for pregnancy xKimmi if there is ANY chance of that (especially as your fertility increases as you lose weight).
