What Are The Side Effects Of Susten?

My TORCH test is positive. Last month my doc had prescribed me Famtrex 250 mg, Rovomycin Forte for 10 days. and in this month my doc prescribed me Letrozole 2.5 mg and F-Gam. He evn told me to take SUSTEN 100 mg. Is Susten harmful for me? What are the side-effects for for it? How does it work? I've not even stayed pregnant since I've been married for 4 years now, is there any chances of me getting pregnant after taking this tablet?
