Late period/negative tests

Rachel • Loving wife 👰🏼 Patiently waiting for our rainbow baby 🌈🤱🏼

My period is 17 days late. Every test I take is negative. Wake up nauseous, fatigue, sore breasts, back pain. Has anyone had this happen?? So confused/ frustrated!

Update, when I go to the bathroom and wipe there is a small amount of brown discharge 🤷🏼‍♀️?
