TMI - implantation bleeding????

Rae

So when I’ve went to be bathroom twice today and wiped and the first wipe only I have this brownish discharge. AF isn’t due until 2/19, ovulation was 2/5. I also had some light cramping and bloating last night, and my boobs are just a little tender. I usually don’t ever start AF early, and I NEVER have cramps until about day 3 of AF. Everything I’ve read says that implantation bleeding is usually pink, but this is obviously brownish. Just curious what you all think. AF early or IB??? Thanks in advance!
