Welcome to HealthcareMagic.
As your Gynecologist has done USG , she could have seen if there is any pregnancy
then itself.If pregnancy has happened by then , the drug is not indicated.The chances of pregnancy occurring while take modus
10 mg are less. Modus 10 mg when taken during pregnancy can cause fetal abnormalities.I advise you to revisit your Gynecologist and get USG repeat scan and then opt for better choice base on USG.
