Please help! I'm freaking out

Em

So I'm so depressed and stressed right now. I'll be 12 weeks Tuesday and today when i went to the bathroom I had a watery brown discharge. After wiping about 10 times it went away. I have zero cramping but I'm super anxious. I obsessively keep checking and when I wipe there is nothing but if I stick a tampon in and pull it right out there is brown and dark brown discharge and even a small speck of pink. Has anyone else had this and everything was fine? And no I haven't had intercourse for about a week so I know its not from that. And last week we saw our baby everything was perfect. This is my third I've never miscarried but ive never had anything like this.
