I just filled the script but I am confused

I have been on Dr Google and read the info sheet I got with it and some say it is ok while breastfeeding while others say no go
Does it make any difference that it is the generic brand Diaformin??

It wasnt my normal Dr but I did say earlier on in the appt about my still feeding as my iron is still low but im taking ferrograd.

So yes or no??
