My naturopath is not covered by insurance so I totally understand how disappointed one can be by that. I'm currently seeing him once a week for chiropractic adjustments (I have a hypermobility disorder and regular adjustments are keeping my joints stable enough that I do not need heavy duty pain management, braces, or any sort of physical therapy beyond what my chiro/naturopath has prescribed.) and just general overall health care. Which runs up to a couple hundred bucks a week if you include supplements and treatments. But it's helping enough we feel it's worth the cost.
As far as my issues, I have had 13 miscarriages with 7 of those being blighted ovums (my left ovary only makes rubber eggs apparently), a couple of chemicals, and 2 twin losses between 4.5 and 10 weeks. I've also had a 14 week loss. We know my hormones aren't balanced generally but I tend to be estrogen dominant and have low progesterone when pregnant. When I'm not pregnant, I have mostly 'normal' hormone levels. Whenever we've tested my AMH, LH and all that, they are normal. I've also had a normal ovulation nearly every month and my cycle is regular enough, we do not suspect PCOS, premature ovarian failure or endometriosis. I was told I was entering early menopause a year ago but it was more my body's way of saying "I am tired of recurrent pregnancy loss. I need a break." than me actually being in menopause because I'm currently 17 weeks pregnant with a surprise baby. In that last year, we've learned I have a hypermobility disorder, genetic intolerances to several foods, a digestive disorder that leaves me deficient in certain vitamins, and a thyroid disorder (Grave's Disease). I also have a clotting disorder called MTHFR which affects not only clotting but leaves me chronically deficient in folate. My thyroid disorder likely plays a role too but since we didn't know about it until last year, it's hard to say just how much of a role it has played in all of this. Most of my losses are due either to it being a blighted ovum (which is due to left side ovulation) or the folate deficiency and I haven't been on a high enough dose of my special folate supplement. My 14 week loss has been attributed to a genetic abnormality and/or a blood clot near the placenta but testing on the baby came back inconclusive. My twin losses were due to at least one twin being genetically abnormal. We also have a very high risk for genetic birth defects, specifically heart defects and various Trisomies, as well as genetic disorders like Down's Syndrome and Cystic Fibrosis.
Having said this, do I think the naturopath can help someone in your situation? Yes. I've seen many instances where naturpathic medicine has helped a woman with infertility and I myself have benefitted from it to a degree. But since nearly all of my issues are genetic in nature, there's only so much we can do to help me. Since your issues don't appear to be genetic, I would say there's a decent chance you'll have at least some luck with this path. I will say that, while I firmly believe I would not have children if it weren't for naturopathic medicine, it is not a cure-all. The amount of luck you have with it will depend on many variables and some have much better success than others. I know a woman who dealt with recurrent miscarriages until she saw a naturopath who had her vitamin/mineral levels tested. Turns out she was incredibly low in manganese, calcium and a few other things. She started supplements and got pregnant with their first child within 6 months. She now has 5 kids and hasn't had any further issues. I also know a woman who has had unexplained infertility (the 'cannot get pregnant' kind) for years. She came from a large family of 14 or something and many of her siblings have several children. Yet she has only had 3 and they are several years apart in age. She's seen 4 different naturpaths that I know of, two homeopathic practitioners, and at least 4 different medical doctors trying to figure out why she doesn't get pregnant easily. No one can find a reason for it and, while naturopathic medicine has helped ease many of her other health issues, it hasn't done as much to help her get pregnant. She only 3 years older than I am but she's pretty much given up hoping they'll have more kids because it's just not happening. But she hasn't stopped searching for answers despite it all. And that leads me to my final thought-you have to be willing to give these methods time to work. I have been seeing my naturpath for over a decade and it's only been in the last 2 years that we've finally begun to figure out the true sources of my reproductive issues. It's taken us this long to clear away all of the other health issues that were masking the real problems I was dealing with. I am hoping it isn't the same for you and as I said before, I am not the average case because many of my issues are due to genetic weirdness.
Good luck!
