Implantation bleeding or AF...

El
I'm somewhere between 13 and 20 dpo (I use 3 different <a href="https://play.google.com/store/apps/details?id=com.glow.android">fertility apps</a> and they all say different, my luck) Last Thursday I started feeling nauseous and bloated, hasn't stopped. And my nipples have become increasingly sore since then. Then on Friday my lower back started to hurt, which is weird for me. And I saw a few very small light pink spots when I wiped on Friday, only once. And I've been crazy tired, I'm usually tired but this is more so than normal. Today I've been having brown spotting, like all day but just when I wipe. Normal pre-AF spotting for me is pink/red and once just a little bit then there's a need for the mega super size tampons. Fingers crossed but don't want to get my hopes up. 🌈
