Brown discharge

So I'm about a week late and I have been noticing brown discharge only when I wipe. It's not even enough to use a panty liner but I do just in case. I'm feeling extremely bloated but no cramping or other usual symptoms of my period coming. As of today I noticed a bit of pink on the paper when I wiped but nothing more. I've been with my fiance for 3 years and we aren't exactly TTC but are very open to having a bundle of joy. Somebody give me some advice as to what this may be please!
