you clearly have a sign of pregnancy. your late thats like the number 1 and key symptom of pregnancy. and you get pregnant through unprotected sex. so its very possible you are pregnant.
you should really go to the doctors
Brown blood usually just indicates old blood that is shedding down. Have you taken a pregnancy test yet? The smell could be an infection, bacterial vaginosis usually smells like fish. You need to take a test, and if it is negative, go see your doctor for treatment.
I am aware of the risks of having unprotected sex. But as far as my knowlege is concerned deep brown blood is not one of the usual symptoms of pregnacy, a light pink color is. Usually the type I experienced means a miscarrage according to some of the research I have come across. But miscarrage is not really a possiblility. I had absolutely no signs of pregnacy and had a normal period the month before.
Late and unprotected sex don't automatically mean pregnant either.
Being late could also have other factors contributing to it such as stress or unhealthy weight.
I am not an uninformed woman. I am in school for nursing but I don't really feel comfortable going up to my professors and telling them this information considering they actually know who I am. I had a smelly discharge that comes and goes. I was thinking bacterial infection but what about the brown blood?
What are other theories?
you might be pregnant! your late and you are having unprotected sex. take a TEST
