I had peed into a cup and was going to dip my OPK into it, but when I sat the cup down on the edge of bathtub it fell down onto our carpet 😡!! Now there's a big urine stain. What do I use to get it out and so it won't stink? I immediately poured some carpet cleaner stuff I had onto it and then laid a towel down and stomped over it to bring it up. Any stronger cleaners I should use? Thanks ladies!!
