good evening doctor. I'm 19 weeks pregnant having twins through IVF. I've been taking: proluton depot 500mg I/M inj weekly, folvite tab once daily, shelcal tab 500mg twice daily & ferinia XT tab once daily. one week before my doctor has suggested to take ARG 9 sachet twice daily for 1 month. Should I take ARG 9? can it be harmful to fetus in any way? my age is 39, weight 54.5 kg, height 153cm and it's my 1st pregnancy. kindly help me.
