I lost my virginity six days ago,i have firm breast and my stomach feels firm am i ok?plz help me?

Your post is vague on details. If you think this is pregnancy it is too soon for the placental hormones responsible for symptoms to be present from an embryo that would just now be attaching in the womb. That would be expected to take another week. Take a urine pregnancy test. These are positive when symptoms are due to pregnancy. Either wait it out for now or see a doc to decide what is happening
