Hi @Groundhoghcg.
I'm sorry to hear about your miscarriages 😢.
Are you my twin? I've also had numerous miscarriages (4), have one child and am under Dr Thum with exactly the same diagnosis and treatment.
I'm 6+3 pregnant just now but think I might currently be experiencing another miscarriage - bleeding started a few hours ago, I feel numb and can't believe it... I actually have a thread going myself but can't face updating it.. (but will send you a link as several people on the thread rook pred and found it very helpful).
Anyway, as for your question: I had the exact same dilemma as you. Due to concerns about my weight (I'm overweight unfortunately due to years of treatment for an autoimmune condition and mobility problems), Dr Thum and I decided that I would go on pred very briefly only ie from BFP to 'tie me over' until intralipids could be arranged. I'm very far from his clinic so arranged intralipids locally to me - but since I can't have the private nurse who has agreed to do the intralipids on call 24/7 in case of a BFP, I asked Dr Thum if I could go on pred for a week or two between BFP and starting intralipids (which seems to be a vulnerable time for me as I seem to have early losses).. to bridge the gap between BFP and intralipids. Dr Thum was happy with this plan, I got my meds, and when I got my BFP I arranged the intralipids.
But I then suddenly didn't want to do intralipids anymore; just a gut feeling. Plus steroids suppress symptoms of my autoimmune condition so I worried if we stopped pred my auto immune issues would flare.. It just suddenly felt strange swapping a treatment that was working for another one. At that point I was approx 4.5 weeks pregnant, so I had another consultation with Dr Thum. He was fine with me staying on pred as long as my weight doesn't go up significantly and my BP is okay, so am monitoring both and so far so good.
I don't seem to have the moon face yet. I have been on steroids before and have definitely had it but at that point I wasn't very careful with eating whilst I have been very careful with my eating this time round. I am feeling quite hungry but have just tried to eat healthy food and not over eat. I had a few nights of waking up in the middle of the night and not being able to get back to sleep which I'm sure was due to the steroids but that seems to have stopped. I also thought at one point I could feel my heart beating excessively but again I don't notice it anymore. Overall the pred is making me feel really good (it prevents symptoms of my autoimmune condition) so that's a bonus and I seem to have a lot of energy and zero morning sickness - usually pregnancy makes me very ill. And it's a lot less expensive.
Having said all that, since I might be miscarrying it might not be working for me so I might not be the best example. But lots of folks who are on it seem to say it's what made the difference in their successful pregnancies..
One other negative is I currently have what must be a chest infection, and I'm really quite unwell with it which I assume I picked up because of massively lowered immunity.
I hope this is helpful. I'll try to post a link to my (not yet updated) thread so you can see what others have said about pred (haven't seen anyone comment about intralipids)..
