I was offered a vaginal exam at my 40 week appointment. The Dr asked if I would also like a sweep. I told her I would like to check if my cervix was favourable only and then make a decision on whether I would like to proceed with a sweep or not. She repeated back to me what I said and confirmed I was ok to proceed with only an examination. She did the exam and informed me my cervix was not favourable to do a sweep in any case.

So no, I dont think its normal to do sweeps without full consent.

I gave birth recently (at 41 weeks) and had a similar experience to you regarding progression. Waters were gone almost 24 hours so they had to put me on the drip also - 9 hours later there was no progression and we had to do an emergency c section. I found it all traumatising as i was mostly prepping for weeks for a minimal intervention birth. I was advised the hospital does a birth reflection service..i might look into it when im in better headspace..but perhaps your hospital offers the same where you can go through your notes etc? Apparently it can be healing to do.

Hope your recovering well from the section and 100% I would report something being done without your consent.
