I've read everything... I'm going to try asking again, maybe someone had an injection for lung opening in a baby at 27 weeks? There aren't really any grounds for this, only one late miscarriage. Everything is good now, no protein, no salts, no swelling, no pressure, the cervix is good... I read online, and now I'm scared. I know I shouldn't read it, but nobody answered before that. Who has experience with this? My nerves are already ruined.
