Stevie's nails were really bad when I got him about two weeks ago. I waited about a week before I tried to cut them. I also had to give him a bath (he was not well cared for before I got him) so I did it after that. The water made his nails softer (he was only in the water maybe five minutes) and that made them easier to trim. I would also get someone to help you. Hold your piggie cradled in your arms like a baby and have someone else trim the nails for you. Some people put a towel over their piggies head to help keep them calm. If you don't get them all trimmed the first time, don't worry about it, just try again in a couple of days.
