Having coil removed... Then what?

Hi all
​Am planning on having my copper (no hormones) coil removed at the beginning of April. Any tips of what people call the 12 month pregnancy.  Ie the idea that you should spend 3 months being really healthy-no alcohol, caffeine, pre natal vits etc etc and then start TTC so you have built up a bank of vitamins/minerals etc ready? Any views? Anyone had a coil out? Does it hurt? Do you bleed? Should you wait for a normal period before TTC? Does having it removed mess up your cycle or anything? Help please
