hio ladies i bought a bbt thermometer off ebay only its only a 1decimal place one i.e 36.4 not like 36.47 does this make a big difference would i be better off not temping with this and getting a 2decimal place thermometer or can this ione be used thanks all

It can still be used, although I would return it if I were you. BBT thermometers are exactly those with 2 decimal points. If they advertised it as BBT, then it's not matching description.
