Need Advice on Duphaston , PLEASE!

History : I miscarried in August in week 5/6. I miscarried the very same day my intervaginal ultrasound was done after i saw a positive on my home pregnancy test. My doctor advices to try in three months and asked to take falsafe -L and Raricap. My last period was on sept 9th and on oct 6th i took a home pregnancy test and it came positive. Im still continuing to take Falsafe L and Raricap. I decided to visit a OB after i complete my 8 weeks this time. I dont get any pregnancy symptoms other then sore nipples and breathing high after climbing stairs. I checked with a doctor on Practo if i should take any blood test meanwhile to see my hcg levels before i visit for sonography. She advices that its not necessary and asks to take Duphaston twice a day along with my existing prescription (folsafe L and. Raricap) Please advice. I cant afford to harm this baby in anyway
