HELP!!!! PLEEEEEASE

So I had my period already (it lasts about 4 days) and I got it on time (the 5th day of my sugar pills) but I'm super stressed out. I've been crying non stop, my heart won't stop racing, I've been having problems with my boyfriend.... and today I'm on my 3rd blue pill the first week, I haven't had any sex at all since last month. And I noticed I have a lot of discharge like it looks brown? And when I wiped I noticed like it looked like a hint of blood, like a yellowish discharge and I've been so stressed...I've been using the bathroom a lot like I poop a lot lately. Not tryna sound gross... Is there any chance??? Or am I just stressing too much??? :( I haven't been drinking or eating much of anything...
