You're very welcome. It's normal to feel the way you're feeling--not easy, but normal. You're scared and worried about your baby and your other children, and as moms we do that. Great doctors understand that and will partner with you to ease your stress and help you understand everything going on. Although there are never any guarantees in life, I hope that you can find comfort that you are doing everything for your children and yourself, and that you have partnered with a healthcare provider who is helping you along the way.
Glad that you got your lab numbers and that you're going back on Friday. If I were you, and if anything concerns you, I'd call your healthcare provider. I had the itchy and dry hands, too, in my case it was dry skin, but my perinatologist told me that he was glad I brought it up, because it could have been something more serious. Like I said, you seem to have a great partnership with your doctor, and I'd continue to let her know if anything is bothering you. I know you have an appointment on Friday, but if I were you I would get that peace of mind and call if anything felt worse or off. As the Preeclampsia Foundation says: "Know the symptoms, trust yourself." You've been very proactive to this point, so keep it up. Your fourth child will be here soon

My twins with my first pregnancy were induced. I had an awesome MFM and nursing team, and they helped ease my fears throughout the whole process. They told me every step along the way, and it helped ease my stress. I'd always ask: "What is that for? What are you doing? Is there a downside?" And my nurse would tell me.
In terms of induction or C-section, when you trust your doctor whole-heartedly, you can come to a decision of what's best for you and your baby. From the sounds of it, your doctor has a good feel for you and your pregnancy, and on Friday (or sooner, if you feel the need to call and she feels the need for you to come in), you can go into induction or whatever your doctor recommends with both eyes open knowing what to expect. Ask them the questions that will ease your mind so you know what's going on.
Wishing you the very best, peace, and cheering you on as you get closer to holding your baby girl,
