She absolutely can get pregnant the day
before her period. Women can get pregnant
any time of the month. That means we can
get pregnant before, during, and after our
period.
In a typical 28 day cycle, ovulation (when
the woman is most fertile and most likely
to get pregnant) happens around day 14.
However, few women are like clockwork.
That means our cycle might not be 28 days
long, and we might not ovulate at day 14.
Some women even ovulate when they are
still bleeding from their period. Also,
sperm can live for a few days inside the
vagina. That means you could have sex a
few days before she ovulates (becomes
fertile), then that sperm could still be
in her vagina a few days later when she
ovulates resulting in pregnancy.
It is very difficult to tell when a woman
is ovulating. Most women have no idea
when they are. So protection needs to be
used every single time no matter what
unless you are trying to get pregnant.
The bleeding she is experiencing is
probably her period or vaginal tears from
being too dry during sex. If you two had
sex for the first time tonight, it would
be too soon for her to have implantation
bleeding. If you two have been having sex
before that, then it could be implantation
bleeding. The only way she can know is to
take a pregnancy test.
