Ond rwy'n annog pobl i wneud yr alwad os ydyn nhw'n poeni. Paid ag ofni bod yn anghywir, beth os wyt ti'n iawn? Mae modd rhoi gwybod am bryderon yn ddienw.
But I urge people to make the call if they are concerned. Don’t think 'what if I’m wrong?' Think 'what if I’m right?'. Concerns can be reported anonymously.
