Why Did Rogam Shot Taken For Threatened Miscariage Cause Voice Loss ?

I just turned 30 and also had a divorce and custody battle which I got custody so my stress level should be down. on may 22nd I went to the emergency room and found that I was 12 weeks and 6 days pregnant with a threatend misscarriage. I got my rogam shot but have now lost my voice almost. Another big concern I have is I was taking yaz, sonota, clonazapham, and not often but napraxzon 4 migriane headaches. I started having a toothache before knowing I was pregnant. Im so afraid him or her could have serious problems.
