Implantation bleeding?

Ashley • Prego w/ #2 🤰🏻Hunter 12/31/2019♥️ 👶🏻 National Guard Army wife 8/18/18💕 Fertility treatments also

I’m about 7 days past the sex that would cause implantation bleeding. I have pink discharge but I took a test just to see and it was negative

Anyone else have any ideas? I keep cramping slightly but my stomach is all messed up too. 😩 any other ladies going through this???
