You better use protection because you probably could become pregnant any time you have sex without it. You might not be and you might be.
the only way you can tell if your pregnant with your period is if you miss it.

With or without protection you can still become pregnant.
There are no days before your period, when you already are pregnant. As soon as you are pregnant your next due period at the 4th will not come. When you are without periods for 2 months, it is very likely that you are pregnant. Many women don't know, that after 10 days after their last period, they are in a period of another 10 days that hey can become pregnant. Mostly it is only 7 days. So that means that 21 days between your period you cannot become pregnant. Short: Period + 10 days free. + 8 days pregnancy possible. + 10 days free. Dr. Phylopi
