Is there any differences between taking non-stop contraceptive ld and seasonique for stoping my periods for 3 months?

Probably not: I'm not familiar with Contraceptive LD, but if it a low -dose monophasic (dose doesn't change during month) combination (has both and estrogen and progestin component) OCP, it will probably work. Most pills have 3 weeks of active pills and one week of placebo. Don't take the placebo pills, and don't take a break before starting the next pack. You will need 4 packs of pills every 3 months.
