Reddit reviews Not Broken: An Approachable Guide to Miscarriage and Recurrent Pregnancy Loss

You should see an RE and get tested for recurrent pregnancy loss. I've also had 3 miscarriages. I found that this book was helpful: https://www.amazon.com/gp/aw/d/0998714607/ref=mp_s_a_1_1?ie=UTF8&qid=1497498694&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=not+broken&dpPl=1&dpID=41AHrbC-dyL&ref=plSrch
I skipped the chapters on eastern medicine and I don't think you should stress out about the lifestyle changes she talks about. Miscarriage is out of our control and there's nothing you could have done to prevent it. Sorry you are dealing with this.

I'm so sorry this has happened to you. It is so painful.

Here is a book that I have heard about but haven't read myself that's supposed to be helpful. When/if you're ready. https://www.amazon.com/Not-Broken-Approachable-Miscarriage-Recurrent/dp/0998714607?_encoding=UTF8&psc=1

It looks like you and I have some similar history - I'm also 35, TTC for 3 years, and have had 2 MMCs and CP. We are also preparing to begin IVF this summer. My RE is very skeptical about these kinds of somewhat controversial treatments since the research does not robustly support them and anything that affects your immune system has some fairly sizeable risks associated. Rather than doing any of those treatments, we are opting for IVF with PGS.

I actually just read a new book that addressed this some also, it's called Not Broken: An Approachable Guide to Miscarriage and Recurrent Pregnancy Loss. The author is a grad of the Stanford RPL program and runs an RPL clinic in Seattle. I thought the book was pretty good - it is grounded in evidence and does a nice job incorporating stuff about treatment, psychological/emotional impact, and the risks around controversial treatments. For the intravenous intralipids (p. 55) she says: main use is for patients who cannot use their digestive tracts to gain nutrition and to clear toxic overdoses of some medications; a few small studies show that blood levels of NKC are lower after (although she is skeptical of the NKC stuff too, and blood v. uterine NKC levels vary a lot) but no large studies to support; immediate side effects can include - flushing, dizziness, muscle pain, nausea, and vomiting; long term side effects can include - liver and kidney dysfunction and increased risk of blood clots.

This all is a highly personal decision, and I know the very strong desire to do anything to prevent another miscarriage. For me, the lack of evidence and risks do not make it worth while. I've sort of come to accept that a large majority of MCs are because of genetic problems in the embryo.

Check out “Not Broken” by Dr. Lora Shahine. It covers every known cause for recurrent loss and explains all of the tests REs typically run. It’s thoughtfully written, really easy to read, and based in science and medicine.
I had been (erm...have been) obsessing about my unexplained RPL and read this book in a day. It was fairly comforting.

So sorry for your losses, hope this helps.
