This is the context which plays a vital part here. If you are discussing any gynaecological problems, then it should be either Bachchdaani Dee Greeva OR Garbhaashya Dee Greeva.

On the other hand, if you are refering to it in general term, lthen it should be either Dhaun or Gardan.

It seems that you posted this question in this segment i.e. Hindi>Panjabi due to some mistake otherwise if you would have posted in English>Panjabi segment, you could have got the answer much earlier.
