Blood On Couch!

I have a situation and I need some help. I was sitting watching Friends on my TV on my parents couch when I felt like I leaked through. I ignored it because I had JUST put a new pad on. I sat up and I had two small stains of period blood on the couch. My Mom went upstairs to take a shower, and I flipped the cushion so that no one would see for a little bit. I went upstairs to change my leggings and my brother went on the TV and is playing video games. I’m sitting next to the stain with a small towel over it so he doesn’t suspect anything. I don’t know what to do because I don’t want to make it obvious I leaked on the couch! I need your help ASAP! Thanks 😅
