need suggestion

my daughter is pin a family way she wants me to be there as i m her mother & motherly feelings r really very strong so she send me all the papers along with sponser letter. but here as it was my first time i didn't know about what to give with application form on the first window. (outside). i just gave my form, passport and drafts. and at my interview time , due to this i think now they guess that there is no reason of coming back and they asked me few questions regarding my daughter like why u send ur daughter so far, through what purpose she go there and why u choose america only to send her there , i replied them but atlast they just said me that there is problem in ur convincing ,and they gave me 214(b) form. now u pls tell me where was the problem is this the reason of mispresentation or something else. and u can ask if u want to know other more details.

dont ever tell INS u r visiting US because ur daugheter is pergnant..they will reject it saying US has very good medical facilities which will take care of ur daughter..apply agian after some time..
