Exercise after ectopic surgery

[Lunasea]

Hi im looking for advice on what exercises i can do to strengthen my tummy and lower back. The surgery to remove my right Fallopian tube took place 9 days ago. Im still a little bruised up but i am loosing my core strength big time and my lower back hurts. What gentle exercises can i do to help me get back my mobility? Or is it too soon and i could injure my recovery? Thank you
