Atkins can be super good for you if done right (as in you've probably talked it over with a doctor) so I'm not going to say you shouldnt do it (I worked in a medical nutrition lab for 4 years, so I know it's a good thing if carefully undertaken) That said, I personally don't know that it is Directly related, though the sudden diet shift coupled with the proximity to your period could have confused your body since it has specific needs in order to menstruate. It's also possible that even though you are taking a vitamin supplement it is being absorbed differently than normal which could cause discomfort. Lastly, you could have changed your body's internal pH which could make things uncomfy by letting things that don't normally live there get going.

Sorry it's so long, and not specifically helpful, but in summary, yeah they could be linked :)
