Ttc 9 years

Hi im ttc for 9 years but for the past 5 years i stoped doing fertility treatments because.my last iui broke me and stoped and hoped for a natural conception but i feel like im not ready to give up and going to try ivf This year , my question is do.i have to restart all over again before i got my ivf ? Hycosy? ,amh , follicle count hormone checks? . My amh and follicle count egg reserve was good my tubes was open everything seemed fine . Only thing now is i feel like i have fewer days on my period it was 3 now i fully bleed for one day and light bleeding the following.then it stops?
