Implantation??

Christina • 🇫🇷❤️👧🏻🤰🏻 Ma vie est magnifique.

Yesterday I had very light pink spotting and cramping and today I have super light brown spotting with mild cramping. AF is due, according to glow, in 4 days. Could this be implantation bleeding? I have the clearest skin I've ever had in my life and I've been bloated for a week. My boobs hurt too and I've felt a little nauseous and dizzy. Thank you!
