Has anyone heard of getting Reclast 3 months after the first infusion?

Has anyone heard of getting Reclast again 3 month after getting my first dose of 5mg IV? I switched off of Prolea after 3 years due to hair falling out and after 6 months got my first Recast infusion in April. Now my 3 month C telopeptoide is much higher than my endocrinologist would like and she wants to re-dose me now with Recast because she thinks my C-telopeptide is much higher than she was hoping for. 3 months ago my Collagen Type 1C-telopeptide was 61 and now 3 months later is 477. 3 months ago my P1NP was 13.7 and now 3 months later is 32.8. I never had any side effects from my first dose of Reclast but from everything I read the dose is 5mg once a year. I think the higher 1C-telopeptide is a rebound from going off Prolea but should't the Recast takeover? I don't want to lose any more bone....Uggh, so hard to know what to do.
