Af is two days late I just took a hpt its negative ! ! ,

I been getting light cramping on && off nothing major the last few days but today I didnt have any . Last 3 days creamy discharge but today kinda brown discharge, my stomach is burning up hot to the touch . but the rest of my body is normal 😫 I've never experienced this. My cycle comes like clockwork 😫😫, how much longer should I wait to take another test ? Or go to the doctor? Something is up 4sure 🙏🏿🙏🏿🙏🏿😫😫💕 baby dust
