If by 'safe' you mean no risk of pregnancy - no, this is not true.
During the average 28 day cycle a woman is most likely to be fertile between days 7-16 - with ovulation occurring around day 14 (a viable egg may be present for up to 48 hours) and up to a week beforehand when fertile quality cervial mucus is present. During menstruation is one of the times a woman is less likely to get pregnant as there is no egg present, although if the menstrual cycle is shorter she could still have fertile quality cervical mucus during menstruation so pregnancy is still a risk. Five days after menstruation would be right in the middle of the fertile phase. Although this is the average cycle, not necissarily true to your cycle.
Unless a woman uses Fertility Awareness Method she has no way of knowing when she is fertile or not, cycles can change a lot so you can't guess fertile days based on your past cycles (this is known as Rhythm Method and not at all effective). If you don't use Fertility Awareness Method then you have to use another form of Birth Control if you want to avoid unintended pregnancy.
What do you mean by safe days? During your period or before you ovulate? Explain please :)
There is no 'safe' period. Pregnancy can occur at any time during your menstrual cycle.
No you are not. The risk is higher in the last days.
There are no "safe" days to have sex. Use birth control.
There is no "safe" time during a month to have unprotected sex!!
The menstrual period is the time in which you are menstruating, I think that you mean your menstrual cycle. Safe days are days you can have sex without getting pregnant, you can only know these days if you were using fertility awareness method as a form of birth control.
immediately before and immediately after a period.
If you mean sexual intercourse then it's unwise to rely on any so-called safe period. Get proper contraception.
You're never safe from getting pregnant. True, at some moments during your period it's a little less likely, but you're never a 100% safe.
There are no totally safe days.
Yes it is safe
If by "not safe" do you mean most vulnerable to get pregnant, then that would during the ovulatory phase of your menstrual cycle. But any day of your menstrual cycle or any other day is "not safe" if you don't use proper protection.
