You're very welcome. So you haven't yet started taking the herbs in your signature? Have you taken them before? Do you know what dosage works for you? Effective dosage of herbs varies greatly from individual to individual just as drugs do.
So I'm guessing this cleanse is some herbs to help your liver and probably some fibre and a laxative? along with instructions to ease up on meat and processed foods for a couple of weeks? It's so hard to know what to tell you without knowing you and what is in this cleanse. it sounds fairly mild and innocuous, from your description, but who knows. Nothing terrible will happen by adding castor oil packs into a regime, but I would still recommend starting off with the CO pack for one cycle (4 days on, 3 off) as that seems to be when it will have the strongest and most noticeable effect on you. Then depending on how you feel on them, add in the cleanse. mizzstee had an ultrasound before and after she started the CO regime and has a lot fewer cysts than she had to begin with, but she's been doing it since late January.
Please note that you should not use Dong Quai in conjunction with Lisinopril.
Your health needs sound fairly complex, especially taking into consideration your desire to TTC in as short an interval as possible. I would strongly recommend that you consult with a naturopath, even if you can only manage a phone consultation.
www.ovarian-cysts-pcos.com is run by a naturopathic physician in Montana who may be able to provide you with some guidance. I don't know enough about Nancy Dunne to recommend her, but she is one of the few practitioners of any modality who specialise in PCOS, so it's probably a reasonable place to start.
Good luck with whatever you choose to do.
