It could mean you're pregnant
Yes you could still be pregnant. You can even still have your period when you are pregnant. If you haven't already taken a pregnancy test you might want to. I had a friend who had her period 7 of the nine months
yes, some pregnant women have there period every month.
Probably not. If you had your period, then you are most likely not pregnant.
Yes, it could do. Take a test
No, not really. Periods can be as short as 2-3 days. If you had a period most likely you aren't pregnant. The first sign of being pregnant is no period.
If you had normal period (not short! not light!) - your chances for pregnancy are about 1%. If you had unusual period + pregnancy symptoms - you chances or pregnancy are 50%-60%.
The short answer is yes. If you have had unprotected sex you could be pregnant.
you would get pregnant
It can by a symptom, but it could also mean you just had a short period this month. Take a home test or go see a doctor if you aren't sure.
Yes you could. Get a test or seek medical advice.
Most probably not, even with such a short period.
