Talk to Gynecologist on Miscarriage

Salam. I had a missed miscarriage in the 7th week of my twin pregnancy. Had a DNC in the 9th week on 25th of may. I got my periods on 26th june. I was advised by the doctors here to get an ultrasound done. Which i did and the reports are attached below. Please check them for me. I had a few deficiencies in my last pregnancy i am attaching the reports below. Please have a look and advice me some multivitamins so that i dont get this problem the next time. Also when is it safe for me to conceive again? Currently i am having only surbex Z and maxfol. I usually get headaches and feel tired. My legs and knees hurt a lot too. Please give me the best advice. Thanks
