Im also on Progesterone Pessaries until 12 weeks as my levels at the time of the first BT were borderline. From everyone Ive spoken to, depending on your protocol the first set of progesterone pessaries are included and the remainder are at the patients cost. The reasoning : its their job to get us pregnant. Progesterone pessaries are to keep us pregnant and therefore not included in the cycle cost.
As for the elevit I buy mine online as it was recommended to be the best prenatal vitamin. Over the past 2 years I reckon Ive spent $500 on elevit alone.
