low oxygen levels

Ok just saw my doctor and I'm 35 weeks. Carrying high baby head down and super good. Had a sonogram today too cause I have gestational diabetes and on metformin. Ok so I'm waking up unable to catch my breath. Super fatigued during the day and I know it's apnea related. However to get a cpap covered takes at least a month and by then I will be so close if not delivered by then. So it would be too late. I know I just need oxygen cause my body is screaming for it as I work in DME so I have all the signs except blue lips or nail beds. Do anyone have any temp solutions since a cpap or supplemental oxygen won't happen? Thanks in advance
