First time for everything I guess

So I’m 36 weeks tomorrow. I’m at work tonight, and just used the restroom an hour ago. (FYI....My four pregnancies prior to this one I never had anything happen until I was in the hospital being induced. So this is a first for me.) I used the restroom here at work and I noticed the toilet paper was a bit discolored. Looked like the faint brownish blood that women will spot before their period really shows up. From what I read online it says if it doesn’t go away after a few hours then call my doctor. Do any of you other ladies have something similar going on or have had it happen before with other pregnancies? Like I said, this is a first, totally new territory for me.
