Yes, they do but I would recommend the ring. More information, here. But the patch works as well – the only negative on the patch is that it delivers higher estrogen than other pills and that puts you at risk of blood clots. BUT it is better than nothing. also, if you are NOT good at taking pills by mouth, you can take them intravaginally or you can also stick them in ice cream, yogurt, food, etc. they are really small. You could also consider the implant but 30% of women will continue to ovulate on the implant, so that might not fix all of the dysmenorrhea. But most of the dysmenorrhea comes from amount of blood, and the implant, IUD, patch, shot, ring, pill ALL decrease the amount of blood you lose and thus, less cramping because less blood to get out.
