Just keep applying pressure with your four fingers on the ventral scales until she relaxes enough for the egg to get within view of the vent. Slow to start and don't let the eggs move back. If you see the egg and not the oviduct skin then you are golden and can continue applying pressure until both eggs come out. If you get the first egg out then don't wait to get the second egg out right away. I did this to give the snake a rest and it the wait can cause more problems. If you have an opening and a clear shot go for both eggs right away.
If the oviduct is blocking it then try a spritz of saline or water with a large syringe. Getting fluid up there does help move things around. I will have to call you to explain further.
Basically try and get the eggs out tonight before the snake gets weaker and things get swollen and more bound up.
I know its seems hard on the snake but in the long run its better to get the stress over with now.
