HI,
Weight loss, glucophage and induction of ovulation with drugs like femera can give good results in women with
PCOS. However if you do not want
to raise hopes too much, you can wait another 7 days and then take a home pregnancy test. For a better confirmation blood test for beta HCG can be done. Hope this helps.
