Low progesterone... troubles

So my dr submitted a prescription for crinone and its so expensive its $458. I can't afford that. For 1 suppository thats insane. I need it to a pre-authorization or perhaps different strength different type. I've searched high and low for mfg coupons. One only dropped it down to $333. I feel a little hopeless since it's the weekend and dr office is closed and to speake to insurance rep is impossible since hours are monday thru friday. I hope it doesnt cause me to miscarry again. Took me 1 yr 1 months to Conceive again. Sorry ladies had to vent.
