HI, I've Placenta Posterior & Cephalic Presentation. I'm In Twentieth

HI,
I've placenta posterior & cephalic presentation. I'm in twentieth week. IN six week I'd TORCH test where infection detected like...toxoplasma IgM-1.39, rubella IGg-89.97,Cytomegalovirus IgG-12.54, Herpes simplex virus1 IgG-4.41.Medicines like Rovamycine fort twice daily & Hucog 5000HP is going on.
In seventeen week I'd 2nd level test which was normal. Also I did TRIPLE MARKER TEST report is yet to come.
I'm am worried for any kind of abnormalities in growing baby. Or it is chance to be safe.
kindly advice.
Thanks & Regards
Shweta
