Yes, this is the time with the highest likelihood of pregnancy (if you mean 5 days after the END of the menstruation).
"Amenorrheic" means "pertaining to the suppression of menstruation other than during pregnancy".
Menstruation is not possible during pregnancy - however light bleeding may be misaken for menstruation when actually it could be implanatation bleeding or spotting due to hormonal changes. If you suspect pregnancy take a pregnancy test, this is the only way to know for sure.
The most common cause of a missed period is pregnancy.
It means you are either having a very light period already, or it is still coming.
It depends on what you mean by safe. There is always a risk of pregnancy. But other than that there is no issue.
Doesn't have to mean anything, The menstruation does that sometimes.If you've had unprotected sex you might wanna take a pregnancy test.
It can mean you are pregnant or not. You need to take a test to find out. Very few women have all signs of pregnancy and you don't mention which they are but many of them are also the same as for ovulation and menstruation.
Not necessarily. It's possible to have your menstruation and still be pregnant. The best thing to do is go to the doctor for a pregnancy test to be sure.
Usually girls have discharge before having firs period - it is very typical pre-menstruation signal.
You could be pregnant , usually after Ovulation your cervix is low hard ,and closed, but with pregnancy it's high soft ,and closed, and your having some pregnancy symptoms too, after you miss your period I would take a pregnancy test. hope this helped
