Why would i have a metallic taste in mouth days while using the ortho evra birth control patch?

Hormones: 1.Certain times of cycle hormones are at a higher level and can promote bleeding gums(severe or very mild). Birth control mimics this effect. The metallic taste could be from the break down of blood...Metallic taste may be the iron in the blood. 2.May also be a combo of this patch with your system...Patches deliver hormones directly and are more efficacious than oral pill, check with your doc.
