I am 52..my period stopped almost 2 years ago and I recently stated having sex...I hear mixed things..is it possible to still get pregnant

You are not considered 'safe' until you have not had a period for at least 2 years so it is important to take precautions up until then, the oldest recorded natural conception in the UK was 59! However, the older you are and the further through the menopause you are the less likelihood of pregnancy occurring.
