Someone told me that travelling to a higher altitude can change your menstrual cycle...is this true?

What cause this? Can a superior altitude create you start your spell even if you freshly finished it?
Answers:

It's completely true. I read surrounded by this backpacking book that said sophisticated altitudes can net your cycle adjectives unusual, and you bleed heavier and longer. It's such a aching, because it happen to me second year on a backpacking trip and I be totally unprepared (and isolated near a bunch of guys! I have to use a set of two of dirty socks); and it happen camp this year...both times completely out of the conventional cycle. I don't know what it is, and I really don't resembling it, but I reckon the best item to do is in recent times come prepared.

Sex Pain?

that isnt true, in my assessment. on complex altitude, nouns pressure change, its more low. so some those experience headache, if they are traveling to somewhere greater. and at hand can also be removal of appetite, nausea or vomiting, fatigue or inadequacy, dizziness or nouns insomnia. so I dont have a sneaking suspicion that that low nouns pressure affects a feminine uterus and hormones.

wel thats purely my judgment.
