Is Receiving Gravibinan Injection During Pregnancy, Safe?

Hi! I got married on 17th Jan of this year, My wife is Pregnant after 1 n half month of marriage. But as she went for a regular check-up to Dr. they suggest Gravibinan to her, On weekly basis. I just wanna ask if its normal? Or any side effect of this injection on Baby. Should we go for this or not. Rite now everything is normal. No problem with her or Baby.
