Sorry I don't have time to research your pill, but here is a link to a web site that should be of some assistance for you.

Pill Identifier - Drugs.com

And of course my favorite question on these are "why" did you see a pill laying on the ground and say, hey, I am oing to pick this up and if it is good take it?

Did you find a pill in your pocket and wonder how did it get there.

I am sorry in all my years I don't remember seeing a pill that was not in its wraper or in its bottle, that I cared to pick up anyway.

Perhaps your boyfriend or girlfriend is taking something?
