Actually Vicodin does lessen your chances of getting pregnant. It messes with your prolactin levels. Right now, I am going to be tested for irregular levels and can not conceive. I was only on Vicodin for 1 wk and it totally screwed with me. All opiates can make your testoterone and prolactin irregular. Tough the pain out, its not worth it. PLus that sh*t is ddicting and makes you too tired to be active.
It is fine to take when pregnant.
vicoden is used during pregnancy so it shouldn't cause an issue that i know of!
