Query over prescribed meds. Mg dha) ?

Hi, My wife had to medically terminate her pregnancy due to multiple complications arising at the end of first trimester. Double marker test reported trisomy 21 and also she has a septate uterus. She had been advised to take below meds during the recovery period. Sysfol Active: Once daily MCBM DHA: Once daily Folivite : 5 mg Once daily Adenosyl -OD : Once daily Vitamin D3 Nano : Once weekly (60k) Meriford-Z : Once daily On checking the salts, i found out that most of the salts in all these medicines are overlapping, hence I am not sure if these all are supposed to be taken. Can any confirm which meds to take and which one to skip? Also, I would want to know if she can consume omega3 capsules (containing 120 mg DHA)? Note: Once her recovery period is over, we want to try again for pregnancy and don't want her to take any overdose.
