Hi oinker. So sorry to read about your 7 m/c. I have no direct experience to share with you I'm afraid. Other than I've been on prednisolone for a year now for respiratory problems. I have no idea how long you would need steroids for your treatment, but if you are interested in effects of steroids during a pregnancy and after, read on. If not please ignore.
I started prednisolone last march when I was about 3 months pregnant. I think I started on 40mg for a short time. For much of the pregnancy I was on about 20mg (my dose varies according to how good my breathing is). For a week after the birth teh dose went back up to 40mg again (since then it has been coming down). Incidentally I have been on 20-30mg omeprazole (reduces stomach acidity) all the time I've been on steroids, to guard against stomach ulcers etc (which completely avoided pregnancy heartburn too), and after being on steroids for 6 months have been taking calcium tablets to avoid osteoporosis in later life.
Ds3 was born a few weeks early following premature rupture of membranes. I don't know the cause of this, never will. Obviously I've wondered if my meds might have contibuted, but my persistant coughing could just as well have caused it.
He is now 6 months old. I am still breastfeeding. He is a little underweight but otherwise fit and healthy. Interestingly he is very strong, more so than my other 2 were at this age, I often wonder if the steroids have anything to do with this.
My dose is currently only 5mg. I am being weaned off them as the cause of my problem was removed a few weeks ago (foreign body in my lung).
Over the last year I have put weight on, which I'm sure is due to the steroids. My face has become round too, but only in the last 3-4 months. Got a bit of facial hair too. Moods have been difficult to control. I certainly feel the slight euphoria when the dose goes up, and am on a downer when the dose is lowered. These changes are noticed within a few days of change, but after a few days I feel more settled. My doctor did wonder if I was experincing steroid psychosis at one point, but was not too concerned. Since then I can only have slight changes in dose, currently I'm dropping the dose 1mg a week.
Unusually for me my immunity is very low, I pick up every bug going. This is partly due to the steroids, but then my chest has been comprimised by the foriegn body anyway. Finally, one other thing to be aware of. Steroids can raise your blood sugar. When pregnant with ds2 I had gestational diabetes. With this pregnancy I was determined not to have it again so paid extra special attention to my diet, hardly any sugar, low gi foods only etc. At 28 weeks the GI test showed I had GD again. They explained to me that if I hadn't been on steroids I wouldn't have had it - the steroids were raising my blood sugar levels. So I had to have insulin for the last few weeks of my pregnancy. I still have to test my blood now (tis ok) and have another GI test when I'm off prednisolone for 3 months.
So in conclusion, prednisolone can be used successfully in pregnancy and during breastfeeding. Thorough antenatal care is crucial (I must have seen gp/clinic once every 1-2 wks). Watch the sugar in your diet, and maybe ask to be referred to a diabetic nurse early on in the pregnancy. Be aware of mood changes around changes in your dose. Report any signs of heartburn and perhaps ask about calcium if you are on them for more than a few months. And invest in a decent pair of tweezers!
Hope this information hasn't been too irrelevent. All the very best to you. I wish you every success. I hope this treatment unlocks those dreams for you.
