Brown discharge at 11 weeks. No tmi pics

I have had crazy allergies this morning. Sneezing light 5 or 6 yimes in a row, pugfy eyes, the whole biz. I have taken an equate allergy medicine. I did read they are safe to take, so idk what to make of this. I went to the restroom and wiped myself and saw light brown discharge along with some mucus. It has gotten lighter like mostly mucus now. Could it be from some sort of irritation? Didnt have sex last night or anything. It is strange because we have been super healthy lately. I am driving myself crazy to think what it could be before thinking the unthinkable.
