Whilst helium is right, you shouldn't panic, it's likely you will have to be your own advocate.
For most women and their babies it won't cause a problem. But for a small number, the consequences can be devastating - there are many very sad stories here on MN.
I was found to be GBS+ with DS2 after repeated UTI's. After doing some reading up I became concerned that a) I labour quickly (my first labour only 5hours 15mins, the next 1 hour 40 mins) and b) I'm allergic to penicillin and the alternative iv antibiotic they use, I think, needs a little more than the advertised four hours to do its thing. I said I was very sure I wouldn't get to the hospital in time for the abs and the mw was indeed blase 'oh, just come along when you first feel anything...' I asked about being induced, the abs started before the induction. 'Oh, that's not a reason to induce'
Fast forward to 40+2 and I go into spontaneous labour. Ds2 shoots out 1 hour 20 or so minutes after I arrive there. IV wasn't even set up. He screamed the place down for 48 hours, his infection markers high by the following morning and so they got me to help get a cannula in him and gave him abs for four days. Totally traumatic especially as I felt i hadn't been listened to and it could have been avoided if I was. he's ok, thankfully, but I still carry sadness/anger over his first few days on the earth because I just wasn't heard.
Currently 22 weeks. I'm definitely being more assertive - and the consultant has agreed that I could be induced, starting abs prior to that. However, he's left the service now so waiting to see if the new consultant at my 28 weeks appointment agrees or if I will have to kick up a fuss
Do some reading and come to a conclusion that works for you. Conversely to how I feel, there are women who fight to avoid the abs, so there are definitely differing viewpoints out there - it's just what is right for you.
