What a day blueberry! Did you get my message? Determined to get you into the Facebook group!
Don't be nervous about your sweep, mine was much better than I expected it to be.
Baby sounds back to back which makes for a harder labour for you, however, second babies onwards have lots more room to move around so they can wriggle into place during labour. So basically, don't worry about it at the moment. Spend as much time leaning forward as you can, on birthing balls, coffee table, or similar, or get on your hands and knees, so baby has enough room to flip around to the side.
Yes, take your bag just in case so you have it with you at least.
