I agree with kangaroomum in general, that it would probably be good for you take some herbs/supplements to support liver and kidneys. Since your mw is a naturapath, has she made suggestions in this direction yet? If not, you might want to get her thoughts on this idea. Or maybe instead, herbs/etc to help with your stress--tho liver support and stress support are not entirely different from each other anyway. As a naturapath, surely she can diagnose and suggest support measures that are best suited to you, individually, using her naturapathic 'eye'.
From what you say about your mw on all levels, it does seem that you have chosen well for yourself, despite her relative lack of experience as a mw. The fact that you like her so much is a good thing--feeling safe and supported and liked is so very important in the Grand Scheme of Maternity Care. Michel Odent says that feeling safe may well be THE most important thing for pregnant women's health--tho I would add that 'feeling safe' should come about in part through mom's informed approach to her care. That is, not just trusting blindly based on personality alone, nor based upon socially conditioned trust in health providers generally--either/both of which can lead to trusting one that has not been carefully examined (as best one can) for their actual expertise and currency of knowledge.
And the above is one of those moments when I am speaking to any/all who might be reading this thread. I mention this because you need to understand that I am not just talking to you. I realize from your posts that some of what I say does not (not so much, not so specifically) apply to you, but could well apply to others lurking. The more you have told me, the more I think that you are taking the most important steps into wise empowerment on behalf of yourself and baby! Yay for you.
I'm so glad to understand that your mw is a naturapath....I was wondering who she was in terms of training/orientation, and was going to suggest that you see a naturapath or chinese med practitioner or someone well-versed in supporting health holistically and naturally. You are already doing so and I think that's great in terms of maximizing your chances of having a healthy normal birth.
As for your former doc and his scary words about pre-e and all the worst-case scenarios--well, that is how docs all too often speak. For one thing, he was simply expressing his fear--and there is a lot of fear at the foundation of allopathic medicine. And of course, an OB does see these worst-case scenarios, because s/he sees ALL KINDS of clients, from the healthiest and most proactive to the most generally unhealthy and simply ignorant and passive about their health (not meaning this as a judgement, it's simply true that some people know nothing about creating health, or lack the resources to get healthier). And while it is true that sometimes, these worst case scenarios DO happen even to women who seem otherwise pretty healthy, that is in fact quite rare. Well, the very worst case scenarios that he mentioned are rare anyway, for anyone--just *more* rare among those who are healthier and more pro-active/empowered, and more common among those who are not healthy nor empowered. If that makes sense.
And secondly, docs are taught, as a specific and focussed element of their training, to assume and maintain control over patients and the dr-patient relationship. The use of fear/intimidation is very commonly understood as a potent technique for gaining control over another. Have you ever watched the TV show "house"? A creepy, horrifying and fascinating study of this phenomenon---Dr House has absolutely no compunctions about utilizing fear to bully his patients (and colleagues), and is well aware of himself in doing so. I doubt your OB is House! Yet he was indeed trained the same general way as House.
So, in a real way I think you just need to let go of that past experience—try to forget about it. Your mw and doc last time were wrong, plain and simple. This is a new deal that need not be burdened by their past jumpiness and mistakes.
I also don’t think that your mw now is being too jumpy. Given that she has done all that I would do (and have seen recommended by the seasoned confident mws I know) in terms of testing, recommendations and such, it seems that she is responding appropriately to your actual situation (not just to a blanket fear). Given that she has indeed done those deeper labs for you, and knows that you are under stress, seems to me that I would do pretty much as she is doing—taking this seriously, but not panicking; making strong recommendations and trying to convey 2 things: 1 is that she is concerned, and why, and what you might do to improve things and 2. is that she still believes/trusts that you are able to take right action to promote and preserve yours/baby’s health.
As for when, and under what conditions and timing, you might choose to seek the new OB's care for this pg/birth, that is very hard to say from this vantage point. If midwifery/homebirth is legal in your state, and this OB really is as cool as you think you can believe, then maybe a very late transfer will not be a problem. Hmmmm....maybe you could try to set up an app't soon to meet with him, and try to get some sense of all this? Not knowing this doc, it's very hard to say whether or not you should be direct about this.
I call stress the Great Ruiner of Pregnancy and Birth (of Life, really! but we are all the more susceptible to the physical/physiological impact of stress when pregnant). So I again say, breathe deep. Take walks or dance to some favorite music every day—*some* kind of enjoyable physical activity to deepen your breathing and improve oxygenation, to improve all of your systems’ functioning, to generally increase your physical strength (which will help you feel emotionally stronger too) and to discharge pent up stress-energy. Feed your mind and soul with positive thoughts, birth stories, with loving words to your baby, your dh and toddler, to yourself. Remind yourself as often as needed (more often needed some days than others, I’m sure) that you DID remain healthy last time, and CAN remain healthy this time as well—that you can trust yourself: you can trust your healthy body with it’s peculiarities, trust your will and actions to take good care of you and baby, and trust your instincts/intuition to guide you to the right decisions each moment.
In my opinion that has only been strengthened by various experiences with clients over time as well as various birth stories by moms that I have read, it is your own instincts and intuition that are your most reliable guides. If/when to seek med care; knowing how you and baby are really doing; what to do, to best serve your own and baby’s health from now on—these things can be well served in part by knowledge/tests/’facts of the case’, but only in part. As you discovered with your last pregnancy, that information went only so far to guide you! So practice listening within, from a calm present space, and trust that you will know what to do along the way.
