Hey shelley

Ok... I had the SAME issue... the bleeding, constantly, and yes... a big ol' 4+ lb. tumor too.. thank god the BIGGER the tumor, it is not dangerous 
I had a FULL ABDOMINAL HYST. exactly 9 weeks ago today... They did leave one ovary.. my dr. told me one ovary acts like two.. andI wouldn't go into menapause.. so far, so good!
Yes... you will have an END... and it is IMMEDIATE! You will have soreness in other ways.. but NO MORE BLEEDING... and get RID of that FIBROID!
I would ask at assesment why they can not go another way vx. abdominal... I had 22 staples right down the belly, like an old fasion C section. She told me they could have done it another way if it was a smaller fibroid. So ask the "size" of fibroid.
Timescale... well.. where I live.. USA.. we do them on Mondays (go figure, lol)... I had to wait 2 months... they do them all day, but only 1 day a week.
I'm sure your dr. will have some ahead of you... but you need the time to "prepare".. so much to Asready, to make it easier for you.
Also... I noticed on this site that some women did NOT clean out there bowels well, they didnt use the red drink the day before..
My dr. told me there is always a chance of "damage to the bowels" if they are not cleaned out well... I did just liquids the day before, drank the drink, and it makes you go to the bathroom for over an hour (on and off of course)... the day of OP, I was totally CLEAN... she said PERFECT!
They should tell you to drink this stuff the day before, and cut off when you stop eating.
Ask how long OP is... good to know.. mine was 2.5 hours..
Ask how many dr.s are in there.. I know I had 2 for mine due to the size of it, and the anathesiologist, and nurses...
Also... if you are worried, and want to use your 'OWN BLOOD" if needed (very few due), you have to donate MONTHS ahead of time... I wanted to, it was TOO LATE.. so if I did have a problem , I would have to use someone elses blood. I am a blood donor, so I wanted to give to myself.
Keep in touch, let us know what they say... there are so many of us here, we have had/or are going to have the same thing.
WE all have great tips, ideas.. all good!
I love this site!
