I feel for you… it’s a scary time and lack of progress is enormously anxiety inducing…
They’re offering you options which you don’t know whether to take or not without knowing what’s best. Every birth is different and you need to go with what feels right for you.
I would try and talk to the midwives to understand if there are any concerns or when these may arise (from memory, they like to see things moving within 24 hours of waters breaking but your own situation may be different).
My experience with the drip was that it was very effective but very intense, and I was prepared to ask for an epidural as soon as I realised the effects (knowing it can take a while for the anaesthetist to be available!)
My second labour went from 0-60 in no time - things may change very suddenly into full labour for you (fingers crossed!)
They ultimately can’t/wont tell you what to do, so do what you can to understand and prepare for. There isn’t a right or wrong answer, for me I made my choices firstly on what was best for my babies (safe and happy - leave them be, any sign of issues, I’ll take whatever’s needed to get us through) and then whatever I needed to cope (ie epidural!).
Your baby will be in your arms within hours, and being in hospital already means you’ll be monitored as much as needed. It’s a really tough part, but you’ll most likely barely remember this after tomorrow, for all the right reasons! If your getting too anxious then by all means take the drip, personally I would take epidural at the same time, although some women are absolutely fine without. Good luck!! x
