bleeding after sex??

hi ladies so i had (protected) sex 2 days ago, my period ended almost a week ago. now everytime i wipe, there's a little blood on the toilet paper, is this normal?? it was kind of rough and i honestly couldn't get wet which idk why, we didn't use lube so is that maybe why? i'm kind of concerned however i haven't been able to make an appointment with my gyno. has any one else had this problem??
