One hour glucose test

Where has your doctor drawn to line to whether or not you need to take the 3 hour test? My doctor uses 129 which seems very strict. I've been reading that most doctors use 140. I got 132 so they want me to take it, but I'm considering passing on it. I talked to my doctor at maternal fetal medicine about it to get his opinion, and he said he would only use 129 as a guideline if I was morbidly obese, otherwise 140 is acceptable (I'm not even overweight). I just wanted to hear what you all were experiencing too. Thanks!
