if someone were to have sex 1-2 days right before her period, is there a big or small chance she would have gotten pregnant?

Short answer: there is a small chance.
Longer answer: the average woman has a 28 day cycle, with her most fertile 'window' on day 14 of her cycle (day 1 being the first day of her period). You are considering sex on day 26 or 27 of a cycle, which is a long way from the most fertile window, which means that there is a relatively low chance of fertilisation.
However, these are *average* figures, which means that whilst they are true for many, they are also *not* representative of a great number of women. Women can and have become pregnant on every day of their menstrual cycle when statistically the odds were stacked against them.
Fertilisation is statistically most likely to happen in the middle of a menstrual cycle, but it can happen at any time because you may have ovulated earlier or later in your cycle, and your cycle may be shorter or longer than average.
Ovulation and the menstrual cycle can be affected by illness, stress, travel and a myriad of other factors. Unless you are very carefully monitoring your own body (signs examined include the position of the cervix, internal body temperature, cervical mucus and others: I stress, this is not a simple process!) you do not know when you have ovulated and cannot accurately predict your fertility window. Even with these signs monitored closely and rigorously, the method of having sex only on 'safe' days is simply not that reliable to use in place of contraception.
[Link](Mouse over link to see full location) , which details some 'natural' family planning methods of examining the menstrual cycle, states that none of these methods are recommended for women for whom pregnancy is totally unacceptable.
This is not to deny the statistical average, but to acknowledge that there is enough of an error margin here that it is simply not worth taking chances unless you are willing to become pregnant.
I hope this is useful information. I don't wish to be alarmist, and hope I have given you a balance between the short answer (statistically you are likely to be okay) and the long answer (this doesn't mean you should do it!).

If people still manage to get pregnant when they use a condom, which is supposed to be like 90-some percent effective- then something like a period isn't really going to prevent pregnancy.
Sex= possible pregnancy.

ANY TIME you have sex, there is a chance you will get pregnant. It doesn't matter if you're on your period or not, about to get it or not, there is still a chance.

There's a very small chance.
