Am 31 weeks pregnant with natural pregnancy. Due to low AFI my doctor has suggested Aminofit tablets along with iron n calcium.. also am taking Argitas L-ARGNINE sachets and ecosprin 75mg.. yesterday I had my scan done with different gynaecologist .. And this Doctor told me to stop ecosprin 75mg and also Argitas L-ARGNINE sachets.. I forgot to ask about Aminofit tablets.. How long in pregnancy Aminofit tablets can be taken. That is till how many weeks of pregnancy it should taken. How long iron n calcium tablets should be taken.. pls suggest! What is the minimum AFI for 31-32 weeks of pregnancy!
