Hi Olga
When you say you were funneled by a lot, what makes you say this? Did they give you any figures? Usually funneling is described in terms of remaining length of closed cervix because it's almost irrelevant by how much width it is funneled. With 23mms of remaining cervix, then I'd say things are still looking good for you. I had less remaining closed cervix with the twins, and I had funneled right to the stitch at 25wks.
Unless there is more to this, then I agree that your Doc is merely playing it safe by admitting you. It's actually not a bad thing to have total bed rest and monitoring - even though I understand that being in hospital is far from fun

If I hadn't had the kids to worry about, I would have preferred to be in hospital - that way I could have driven the medics nuts with my constant questions, and demands for 'on the spot' tvus - I would have been a 'cervix diva' in the truest sense of the word lol
Hard as it is not to worry, and scary to be told there are ANY cervical changes, this is actually a very normal finding for a woman with IC hun. Unfortunately going the whole 9mths with long, closed cervixes just isn't an option for us sweet - and is why the stitch is there, to prevent further catastrophic changes.
The stitch does not stop preterm labour, but it is brilliant in 'suring up' weak cervixes. As far as we know, you don't have ptl issues, your cervix is still closed below the stitch at a very good length, and just 2 days from viability I'd say that's excellent news Olga

. Given you have IC, your cervix is actually behaving relatively well. Hope that helps xxx
