I had exactly this op about 18 years ago now.
I had grown an enormous ovarian cyst and had a strong family history of ovarian cancer.
The recovery time will depend very much on how they do the actual op. If they can do it by keyhole or vaginally that will be all the better for you.
If they have to 'open you up' then again it depends on how they do the cutting. Bikini line incisions heal quicker than up and down cuts. I unfortunately had to have the up and down type and it took me quite a while to recover. I didn't drive for at least 6 weeks and eventually went back to work (non manual) half time after 4 months. With hindsight, I should have had another month off. Anyway, I have been absolutely fine since, except for fiddling around with HRT....first I had to have it to protect against osteoporosis, then I shouldn't have it any more because of increased risk of breast cancer, then I saw a specialist who said I could have it again. All sorted out now and at least the worst of the flushes were covered at the start by the HRT.
You really do have to take things easy after this surgery, but I doubt you will need anyone telling you this as you are likely at first at least to feel totally knackered.
Listen to your body and do not do more than you are able to.
When I got home, I mainly had paracetamol as painkillers which worked for me.....I cannot take anything with codeine in it without vomiting. Immediately after the op I had a morphine pump for a day or two which simply put me to sleep when I used it....great!
All the best. I am sure all will be well eventually!
One last tip, when you do first get up and start walking around, do try to stand up straight. It feels a bit odd and as though you might do yourself some damage but you won't and it is better for you not to hurt your back as well as everything else.
