Progesterone

So i called a couple of chemists today regarding the type of progesterone that i need and the prices for it, most of them come in a box 100, so for the 100mg box of 100 it costs $100 and the price goes up for the higher ones and its not covered by medicare or the pension card, so i need to come up with $100 upfront,
I really cant afford that to be honest,

I know you cant put a price on your unborn child's life, though by the time you pay rent ETC and dont even have $10 spare a week, how am i meant to come up with at least $100 I dont have private health insurance let alone being able to cover the fortnightly payments, plus be on the waiting period for 2 months before you can claim and i need to start buying it 

GRR what to do!!!!!!! plus to top it off the OB isnt giving me the stitch this time :(
