Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.F.
You are a patient of P.C.O.S. using metformin
on and off, and bcp used for few days and stopped. You period is late by 6 days and pregnancy
This is all suggesting your irregular treatment and over enthusiasm to have pregnancy. Over enthusiasm and anxiety
makes any thing negative.
Use the medicine as prescribed by the doctor. Don't worry about the irrigular periods etc on the way of success . If you want to stop some drug also stop it with the advise of your doctor.
As you have the doubt of your pregnancy test, You can have H.C.G.test of your blood, or the U.S.scanning of lower abdomen will definitely confirm the pregnancy if you are pregnant.
Wishing for a quick and positive result of your urge.
