Hello, Firstly, see a specialist for a clinical confirmation of pregnancy. A trans-vaginal sonogram should then be done to locate the gestation sac and to note the age of the pregnancy. If you do not wish to retain this pregnancy, you can ask for an abortion. An induced medical abortion with follow up after two weeks can be done if the pregnancy is less than 9 weeks and later on, surgical abortion is the option available. Either way, have regular follow up as advised and before you have another sexual encounter, start regular contraception to prevent such failures in future. Hope this helps.
