Had intercourse while i was like can i catch pregnant please help?

Like what?: I've never heard of anyone "catching" pregnant but that's besides the point. If you have unprotected intercourse, then yes, you can get pregnant. Will you is another question altogether that can't be answered until 4 weeks later but the answer to can you is yes. So if you don't want to get pregnant, then use some form of protection or contraception, either hormonal or barrier. Condoms prevent stds.

You can catch it.: If you had intercourse and it was unprotected there is always a possibility of pregnancy. You should purchase a home pregnancy test kit and follow the instructions carefully.
