Old blood looks brown. It's a sign that the bleeding has stopped and there's just a little bit of old blood still leaking out.
Yes. More than likely.
It's normal for there to be around 7 days variation from your average menstrual cycle. Your period wasn't late so much as later than you had predicted, that's all.
The length of a menstrual period is typically between 4-7 days, so although 4 days is on the shorter end of the scale it's still perfectly normal. It is also normal for your period to vary from one cycle to the next, so even if your menstrual periods are normally longer than this the occasional shorter period is still nothing to worry about.
You were five days later than you predicted - this prediction was based on your average menstrual cycle length, but menstrual cycles change and they will not be exactly the same throughout your entire life. Anything up to a weeks variation from your average menstrual cycle is normal, also things such as ill health or stress can delay your menstrual cycles too.
Typically on day 14 of the menstrual cycle is when ovulation occurs - when an egg is released from the ovary. However everyone's menstrual cycles are different, if the cycle is longer it's likely ovulation occurs far later in the cycle than this.
Women with severe menstrual pain have higher levels of prostaglandin in their menstrual blood than women who do not have such pain.
You can't get your period any earlier than when it is due.Menstruation is controlled by your menstrual cycle, you cannot speed-up your menstrual cycle or skip phases of your menstrual cycle to menstruate earlier than when you're due.
Basically, menstrual 'blood' is not just blood, it's the remains of the tissue that has built up - so it is not unusual for it to come in a different colour than normal, red blood. Chances are it means absolutely nothing :)
It simply means that you have a 35 day menstrual cycle, nothing more than that. The typical menstrual cycle is 28 days but everyone is different so some women have longer cycles.
It can be caused by stress..if your really stressed about something it can trigger it and cause your period to start again..well that's what happens to me anyway.
Yes, there is a 21 day menstrual cycle. The typical cycle is 28 days but everyone is different and some people may have shorter menstrual cycles than this.
Not more than a tiny amount. Menstrual fluid is not blood, but disintegrating cells.
