14 days after intercourse.
Menstrual blood is actually the lining of the uterus. Every month that a female does not get pregnant, the old lining is "discarded" as menstrual blood.
if you mean menstrual blood, no, they do not
allows the release of menstrual blood and receives sperm during intercourse
menstrual period is the monthly blood circulation of girls while spotting are the release of the blood when you are pregnant
Dry humping, masturbation or having sex with another person can not change menstruation in any way (unless you get pregnant through intercourse).
I would expect that menstrual blood would be a good indication that you are not pregnant. if your not trolling
No, having blood in your urine means it's time to see the doctor. It has to be some sort of infection; viral or bacterial.=When you're pregnant, you will have spotting in place of your normal menstrual cycle.=
Not usually. It normally takes a couple weeks for the pregnancy hormone to show up in a blood test.
Maybe you were pregnant.
Generally fourteen days after intercourse.
No, if you are menstruating then you obviously can't be pregnant. It is biologically impossible to menstruate while you are pregnant, you only menstruate if you are not pregnant. Dark blood is likely just that, dark blood, remember that menstrual flow includes uterine tissue not just blood.
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 :)
You dont get your period while pregnant. The blood goes to the baby.
You cannot get a period while you are pregnant. If you do get what appears to be menstrual blood, consult a doctor straight away.
There is no way to tell them apart, although bleeding from hymen rupture may be very short and spotty.
Brown blood is old blood. Sometimes menstrual blood can pool when you sit or lie down then when you stand up it will flow but will be a brown color. If you have brown spotty blood or a very light period and have had unprotected intercourse, you may want to take a pregnancy test. Sometimes implantation bleeding can be mistaken for a period.
The function of the cervix is to allow flow of menstrual blood from the uterus into the vagina, and direct the sperms into the uterus during intercourse.
The cramps could be from the fertilised egg attaching to the lining of the uterus. This is sometimes followed by some spots of blood but not always.
blood tests are the most accurate. there may be something wrong with your menstrual cycle.
It is possible to be pregnant and have bleeding. See below for more information. http://www.babycenter.com/refcap/pregnancy/prenatalhealth/3081.html http://www.babycenter.com/expert/preconception/gettingpregnant/1460117.html
Yes, implantation bleeding lasts usually and hour or two. It would be hard to distinguish from menstrual blood. Wait ten days after intercourse and take a urine pregnancy test.
The test was inaccurate.
Yes she could be pregnant if you have had sexual intercourse and was not careful. Or worst she could have had a miscarriage if she was pregnant. The best thing to do is to buy two or three pregnancy tests, or go to the doctor. I wouldn't worry though. It could just be her period is changing.
Menstrual blood is a mixture of blood and uterine lining tissue, which is not found in regular blood.
