To confirm that you are pregnant you should take a pregnancy
test at home.
Medication to abort that are called mifepristone and misopristol(citotek) should be taken with the prescription of the gyn . because this medication has side effects and this medication are used for pregnancy within 6 weeks.
For this reason you should go to dr. and consult with him after you confirm at home that you are pregnant.
take care of your self
