How would you compare orho tri-cyclen-Lo vs. Norgestimate- ethinyl est tab for ortho-cyclen? A co worker also told me around Yasmin. There's so many on the bazaar and I am new to birth control pills. Any recommendation?

Has anyone found a remedy for cramps?

Ask your doctor. Everyone responds differently to medications. What works for some may not work for you, and what works for you may not work for others. Ortho is the most popular, i believe, but you may hold to try a few different ones to find the one that works best for you.
