This question is rather popular among women. Quite frequent gynecologists give positive answer on the question. Though the possibility of it is not high and in most cases it depends on individual peculiarities of the body anyway it exists and those who want to avoid unwanted pregnancy should take it into consideration.

Not once gynecologists pointed that unprotected sex during the period faces not only unwanted pregnancy, but significantly increases the possibility of various sexually transmitted diseases. Moreover the risk of inflammatory diseases development increases. It happens in the result of absence of natural protection during the period. The mucus plug covers the cervix and becomes completely unnoticeable and fails to protect from infections.

As far as the possibility of pregnancy during the period is concern, particular caution should take those who have sudden change in the menstrual cycle. In case the period came much earlier than expected and its duration increases. All this may be accompanied by ovulation term changes. Those who have irregular period have more chances to get pregnant. Normally the ovulation occurs in the middle of the period, however many women are not subject to the rule whose period differs from the norm. These women have ovulation not in the middle, but 10-12 days earlier. Nevertheless the case is not only in individual cycle but in peculiarities of sperm lifecycle. The sperm may live some seconds. If the ovule grew up earlier than ordinary term and the sperm contained its activity there is the opportunity of pregnancy. The process of conception will happen after some days of the period, but sex itself may lead to unwanted pregnancy.

Quite frequent it happens in the end of the period, which embodies the output of unfertilized ovule. If in the beginning of the period it is completely impossible to get pregnant due to significant blood selection and highly unfavorable days for sperm and in last days of the period the possibility to save the sperm and get pregnant is higher.

In case after sex a woman has suspicion of pregnancy, to confirm or refute this is possible by means of tests only in two weeks after the presumable date of conception. More exact is blood analysis on pregnancy harmony, which proves pregnancy with greater certainty. This harmony is produced by the embryo membrane cell. By means of this analysis it is possible to determine pregnancy after 6-10 of presumable conception.
