Period

Melissa

So I got off my period on August 23 and when I go to the restroom I'm wiping a little bit of blood and brown blood. So it's pink and brown. Do you think it's old blood or I'm ovulating. My friend keeps saying I'm pregnant but the last time me and my husband were intimate was August 15 and then I started my period August 17. I'm not sure what is going on. Please help with any advice. Thank you.
