There is no definite knowing in this case. You must retest after a couple of days. The only way to know for sure is to see a doctor.
No. Spotting can occur during pregnancy.
Spotting usually happens when a woman was pregnant, and lost the baby/had a miscarriage early in the pregnancy.
Most probably YES
It can be a pregnancy symptom, but just because you have brown spotting it doesn't necessarily mean you're pregnant. Spotting can occur during implantation (where the fertilised egg attaches into the womb lining) Implantation generally occurs around 10 days after sex.
It can mean many things but one of those things is pregnancy so I would go get a pregnancy test or talk to your doctor. Good luck :)
Not necessarily. Spotting can be caused by a variety of issues, including stress, but also including pregnancy. If you suspect you may be pregnant, you should definitely take a test and visit a gynecologist to be sure. Even if you don't have reason to believe you may be pregnant, spotting is something your gynecologist should be made aware of and can help you with.
Pregnancy
It means that you might be pregnant. Take a test
Spotting does not cause pregnancy. I assume you mean "does spotting indicate anything other than pregnancy?" The answer to this is, of course, yes. Spotting could indicate spotting. It's probably you period being finicky, or something along those lines.
Spotting during pregnancy happens sometimes, and doesn't necessarily mean that there's a problem with your pregnancy. Contact your prenatal care provider for advice specific to your situation.
Although birth control is rather effective, it's not 100% effective. Spotting could represent pregnancy or even miscarriage. Some woman believe it or not do get pregnant while on a birth control regimen.
morning sickness is a symptom of pregnancy, but it would be good to check this theory with a pregnancy test
