I had sexual intercorse with my girlfriend and about an hour and half later she took the morning after pill. can she still get pregnant?

Possibly.: The pill is supposed to stop the embryo from implanting so there is no pregnancy, and so a period continues. If she took it that soon after, it is likely that she won't get pregnant. Having said this, it must be noted that nothing is fully 100% and so having her period and a pregnancy test should be also noted to be sure. A visit to the doctor is also a good idea to rule out ectopic preg., etc.
