Prompt pozhajlusta. If I accept the COOK, that, naturally, the cycle is established or installed by duration in 28 days. And what exactly to consider or count then as the beginning of a cycle: the beginning monthly or reception of new packing of tablets? In advance thanks.

About any menstrual on\off cycles time of reception of hormonal tablets do not speak. The tablet is not adjusted or regulated dlinnu tsikla-by them completely stop cyclic changes (t. e. Does not grow and not ovuliruet a follicle, does not change endometry, there are no changes and in mammary glands). If you ask about day or bottom;fundus of a menstrual cycle on any research he all the same is considered from the beginning of a bleeding.
