TheGoodDoc is satisfied with how things are going and says I should keep it up. However, she warned me that right now is a really critical time, since the baby is viable but we really, really don't want her coming out yet (which I'd already figured out myself, thank you very much). So we need to be extra cautious. To that end, she reiterated that if I ever have four or five contractions an hour for more than an hour, I need to call her immediately. She also wants me to postpone unnecessary activities until after 32 weeks--so I had to reschedule the childbirth classes I'd signed up for, switching from December to January. And no shopping for baby furniture--as she pointed out, 32 weeks still gives two months for the furniture to be ordered and delivered, "and if baby comes before then, she won't be coming home right away anyway" (something else I'd already concluded).
I asked about steroid shots for the baby's lungs, and she said that she hasn't seen a need for them yet, seeing as technically I haven't actually had preterm labor yet. But if I do have any indications of preterm labor, she will immediately hospitalize me and give me the shots.
Basically, it's all about getting to 32 weeks. TheGoodDoc joked that she feels like I'm having her baby, she's gotten so invested in making sure I make it at least that long.
In the meantime, I'm continuing to take it easy, count contractions...and making sure to always have enough cash for cab fare to the hospital. Just in case.
