I am feeling nausea from a week n slight stomach pain in d upper side of stomach. [/INST] Hello user, If a young female had been practicing unprotected sex and is not getting any period, the first and foremost thing a Doctor will do is to have a Urine Pregnancy Test, I would also advise you to do the same.Also, you are having nausea feeling, which is seen in pregnant females due to hormonal changes in blood. You are advised first to rule out diagnosis of pregnancy, if it comes out to be negative then you have to search for other causes in your reproductive system, by consulting with a Gynecologist. You don't want to conceive and if at all your test come out to be positive, you are advised to have Medical Termination of pregnancy, according to your countries legislation. Hope my advice helped you. Regards Chat Doctor.  </s>
