Gestational Diabetes

So I failed both my tests by 1 point and my obgyn made me do Diabetes testing 4 times a day since about 13 weeks , I'm 23 weeks now and my blood sugar is typically fine with maybe 1 morning sick being high. Doctors are trying to tell me since it's my fasting ( first test ) of the day that's the high one I will most likely spike around 28 weeks and go out of range all the time - and need insulin. My ultrasounds have me measuring perfect to the day and I have gained 0 weight by making good choices. I don't agree with the insulin taking and want to know have any moms been able to control the fasting number ? I don't want to take insulin and feel very pressured.
