 There's a heightened risk of cervical cancer for women who take Opal. Just read the Opal insert for starters. If you know someone who's on there, maybe you go to the grocery store and open it up and then go take it to the manager and ask, why is this being sold at my local grocery store? Not to mention, hey, you want to have a baby down the road, you are lessening the possibility of having a child one day. We also know that Opal significantly influences sleep and thyroid.
