Dying hair & IVF

Hi ladies. Due to start my first round of IVF mid April. I have highlights that are growing out and naturally dark hair with a few greys here and there (can start to look a right mess if I don’t keep on top of it!). Usually I wouldn’t mind as much but my birthday is in a few weeks and so is my husbands so would be nice to have my hair done. Should I 1) leave my hair as chemicals etc not good for IVF 2) put a dark colour all over and swerve bleach or 3) get my usual which will involve bleach and colour?
