tmi but could this be implantation bleeding

je
I didn't see anything on the toilet paper when I wiped, but I pressed toilet paper on that spot and it showed up brown which is what happened a few months ago when I got pregnant! It would only show up in my underwear. I felt faint cramps earlier and my period is due Feb 5th and I ovulated between the 19th and 23rd. Earlier today I had creamy white cm too. Is it possible it could be IB?! Or could it be spotting because my period is due soon?! I don't feel many symptoms, my boobs are barely sore and I've been super gassy lol
