What are my chances(iui ici} by doing this?

I orderd one vial of washed sperm from a sperm bank, I am doing this at home. i bought the supplies for iui and I know if i dont do it at about 6 hrs before the egg drops its kinda hopeless, but its so hard to know what time that is..so if I dod an iui and then use a instead cup and do ici will that increase the odds???? I know sperm live longer in the ici so maybe if I miss it with the iui I still can have hope??
