Clarkiee, I had a couple of those steroid things 3 weeks ago; Apparently, its not that uncommon. It enhances some surfacant and helps the growth of the lungs in the baby..We did ask the midwife as to why it was not given to e'one then..and she said that it is given when they even remotely suspect that things can develop earlier than normal or for women whose prev deliveries have been like that..
In my case, I was 25 weeks when i was given the steroids; I had had some spotting that day and since it was the first time i had had any spotting, i panicked and went to the ANC centre..They did all the usual tests and the consultant did an internal scan and they couldn't identify a clear reason for the spotting, except for a polyp outside the cervix. So, though the consultant said there was no sign of the blood coming from the placenta or the cervix and thus not signalling any risk factors, he said he was giving the steroids as sometimes bleeding can lead to contractions etc etc..
We were a bit dazed overall to be honest on that day and just took the injections and didn't quiz him much.
But, i have since spoken to a doctor friend of mine as well and its quite safe and has no side effects on the baby; we also got a leaflet from the midwife abt the injection that lists side effects etc; but apparently, with steroid types, the claimed side effects typically manifest only when the steroids have been used for a long period of time.
So, i would say, as far as the steroids go, don't worry. It is more of a precautionary measure that they do, more than anything else.
