With you having your ovaries removed at the same time I cannot give any information on that, and you may want to find what other say on this in this site.
After a mth. you will have accidents that you may not feel. I was tired a lot. My husband drove everywhere, and I always had a pillow on my belly. Just made me feel more comfortable.
All I can say is eat very small meals and you may have to make yourself eat. I would forget to eat and had no hungry pains. If your Dr. tells you to start exercising, make sure your do a lot of slow stretching and walk a lot! Every time you eat YOU MUST WALK and do not forget your fluids.
