Stardust - I don't know if its too late to start the steroids. I was under Mr Shehata and he prescribed 25mg prednisalone from ovulation until positive pregnancy test then increase to 40Mg until week 12 and then wean myself off by reducing dose by 5mg every 3 days. In addition to this I was also on 75mg aspirin, 5mg folic acid and Vit D3 (these were started 3 months prior to conception).
Once I got the BFP, I had to increase the prednisalone and also start 400mg cyclogest (progesterone pessaries). I also had to have an intralipid drip infusion every 4 weeks up to 12 weeks.
I never got past 9 wks with my other 4 pregnancies - so the NKCells were attacking my babies from the start. Apparently the NKCells will continue to be active throughout a pregnancy, although treatment is only necessary up to 12 weeks - after this, your placenta takes over and looks after the baby...
Hope this helps x
