The correct order of reception of pills is indicated by numbers on reverse side of packing. On ending of 21-daily course take break in his reception during 7 days, which the bleeding similar to menstrual, is during. Without depending on that, bleeding developed or not and from his duration on 8 day of interruption, if it is necessary to continue the protection from undesirable pregnancy, it is proceeded in the reception of preparation. New forms of the issue COC appeared now: packing containing not 21, and 28 pills. a 21 pill from packing contains hormones, and 7 are bad containing gland of fumarat. This form is created for comfort rather, that a woman did not forget preparation about the reception. In this case she will not have to “consider” days of admission of pills, and making off the reception of one packing, a woman here will pass to the following.
 There can be different unforeseen situations at the taking of COC.
For example, a woman forgot to take a pill. In such situation a pill must be taken at once, as soon as she will remember it, and subsequent pills should be taken as usual. If an interruption between takings is more, than 12 hours, additional precautionary (for example, contraceptive) measures are needed during subsequent 7 days. Taking of pills from the current packing can be continued. Especially dangerous for missing are the first and the last pills in packing. If an interruption between the takings of pills is more than 36 hours, a contraceptive effect can not be considered reliable and the additional unhormonal methods of contraception are needed, however it is necessary to continue taking of preparation from the current packing (except for the skipped pills) in order to prevent the offensive of the premature menstruation related to abolition of preparation.
If there was vomiting, it is necessary to adopt another pill from other similar packing at once after vomiting. Further the reception proceeds on an ordinary way. It means that one superfluous pill may be needed. For such unforeseen cases it is better to have another packing of preparation. Especially it is actual for those, who takes three-phase preparations, as a pill must be not from any, and from a concrete group, depending on the day of cycle. It is desirable also to use additionally in the nearest days barrier methods (contraceptive).
