I am 26 years old woman and having 6 weeks pregenant. My Doctor diagnosed pcos before 5 months and I have been taking medicines like glycomet 500 SR, B-long and Hyponedd. Now one doctor has refered to take inj pregnyl 2000 units 3 doses each for one week to recede the chance of miscarriage. But the previous doctor suggests to take glycomet 500 SR and duphastone OD. Which is better?
