Hello, I've been reading every letter of the instructions, warnings, and general information on Nuvaring. However, it doesn't say much beyond "ask your health provider" in regards to daily multivitamins. I'm thinking of switching my multivitamin from One-A-Day Women's Multi to Rainbow Light Organic Women's multi and am wondering if either vitamins would infringe upon my Nuvaring use? Will I be at a greater risk of conceiving if I take a multivitamin? One of the points on the Rainbow Light Organic is "Organic digestive and liver support helpts to cleanse toxins, remove excess estrogen and strengthen digestion with liver protective botanicals." In turn, would the vitamin possibly make the low-dose of estrogen in Nuvaring null and void? Thanks!
