My first one wasn't heavy, but everyone is different, she should go to the doctors because 10 days is a long time to be bleeding and she might be losing to much blood. Also if you (or she) is bleeding through a pad in an hour you need to go to the doctors right away.
If you have black blood from your period that is normal if it comes out when your not on your period than go to your doctor and get checked.
This is normal and can be seen at any time in the cycle.
It is normal for menstrual flow to contain the stringy black things you have described. They are probably small blood clots.
Yes its perfectly normal. Its basically rotten blood, that's why your body gets rid of it!
It is not necessarily abnormal, but should be discussed with your doctor anyway.
Not at all. Bleeding red and or brownish black while on your period is perfectly normal because when its red its just blood obviously but if its brownish black its just discharge usually occurs near the end of your period but it happens in between that's nothing to worry about :)
Brownish black blood on first day of your period is normal. This means that it is blood that may have stayed for a while in the urine folds or blood that was there for a while waiting to be released.
no effects
No a "black discharge" is not normal. Using BCP or MAP can cause irregular bleeding and break thru bleeding in the first three months of using OCP.
jK its normal... its just old blood coming out instead of new blood
normal penguins are black and white
No period of Picasso's is called black period.
