I found a pill under the sink that is small, round, light pink/ salmon colored and has an imprint of the number 20 on one side. There are no markings on the other side and the pill isn't scored. I've never seen this before and I'm wondering what it could be. My husband doesn't take any prescription meds that I know of... I'm hoping that this site will let me post a pic of it so someone can help identify it.
