Ya That's Normal...
It is normal to have your period for eight days but only if it is normal - spotting.
No. After a miscarriage you will experience what most women describe as "a heavy period". You may also bleed longer than a normal period. I have heard one woman say she bled for two weeks after a miscarriage. Your cycle will then return to normal, and you should experience a normal period as per your cycle - ie 28 days.
yes
Yes. A period as short as one day is considered normal.
It's normal to have period twice a month heavily just for 3 days only?
Sometimes it will last shorter and if you take birth control pills you will only go 3 days.
yes completely normal. A periods can last anywhere from 3 to 9 days.
only if ur preggers
it varies by person, we are all unique
it depends if it light and if you are very active
Ya that's normal.
Every so many years our bodies change. I highly doubt you are pregnant. I had a baby four months ago and before pregnancy my periods were beginning to change from heavy to light. Be glad you had a light period. Hope for more like that
