Definitely too early for symptoms. Its always possible you may later find out you're pregnant, if your period isn't regular that makes it tricky. The pain could've been, like you said that he was too rough sbd bruised you
It would be way to early to be having symptoms.
I agree i think it is still early to to test but it could happen. the pain ur having might just be because it was your first time. I dont know what could be the explanation for the symptoms.. but yeah id say wait two weeks and then take a pregnancy test. if you get really worried or really bad pain you should go to the doctor.. hope you feel better and good luck
