Yeah I think I might take everything with me in the car just in case I've heard so many stories about people going for their check up and coming home with a baby because they've been induced haha
I have pre-existing diabetes, and my last baby came unexpectedly. I went for a regular checkup and her heartbeat was dipping too fast and too often, so they induced that day. I was totally blindsided and unprepared. So my advice would be to be ready for the unexpected. You could possibly have your baby early. Hopefully all goes well and your sugar will stay in control and lead to a healthy, full term baby.
