I just got done driving 5 hours, and I went to use the restroom and noticed dark brown quarter sized spots in my panties. I am not cramping or passing any clots just a good amount of brown smelly discharge when I wipe. The last time I had intercourse was on Monday June 3rd. This is my first pregnancy so I’m not sure what is considered something to freak out and go to the hospital for, I am freaking out right now. Help!
