I had the combined op at 39 due to 4 difficult births. I was in hospital for 5 days then, but I am sure they will get you out sooner. Do ask the anaesthetitist about anaethesia and ensure you are written up for something strong enough post op. Are you having the op through the vagina, or abdominal surgery?
You will probably come round in a morphine induced haze, which is no bad thing. You will have a catheter draining the bladder, and a drip in your arm. If all goes well that will be it, though you might need a drain if you bled during surgery. They will get you up pretty quickly, catheter and drip removed as soon as possible, and once you have had your bowels open you can go home.
You will feel exhausted, and walking 100 yards will be a huge effort, but just go a fraction further each day. No housework, don't lift anything heavier than a kettle, you are going to need help with washing, shopping, cooking etc, please accept all offers of help. You will probably be told don't drive for six weeks, but with sn automatic car you may be able to drive earlier.
You will be hit be rapid mood swings, especially if your ovaries are going too, crying fits will release tension, don't worry about them.
I have given you a realistic picture, but in 3 months you will be a whole new woman, pain free, energy back, no dragging pains. Mark the date on a calendar and cross off the days!
I wish you well, just focus on you for a bit, which I am sure does not come naturally! 💐💐💐
