@unicorn2016 I took senokot laxatives, I bought them years ago overseas, they took about 15 hours to work. The nurse just said take whatever you need.. Online they say prune juice etc is good, but I didn't try that. Other than that paracetamol, they say don't be a hero take pain relief as needed. Hope you're not in pain and keep drinking water, and getting electrolytes from whatever source, I got Gatorade powder to mix up from Coles.
I was OK though, maybe because they gave me some meds at the hospital for nausea in recovery, and also my trigger was lucrin which apparently eliminates severe ohss, so they prescribe it in specific cases if needed. Downside is it costs $300 just for the one trigger. Bizarrely the medication comes with zillions of syringes and alcohol swabs as I believe it is also for once a day use in certain circumstances, which worried me slightly as I was worried they gave me the wrong thing but rang pharmacist on the day and it was all fine. I still have the unused ovridrel trigger in the fridge. Not throwing out anything in case I need them in the future!
