So confused?

Jaee
I'm on CD36 and I'm so confused. My AF still haven't shown up (which is weird because my period is the regular 30 days). The 2 test I've taken yesterday had faint lines, but the test I've taken today, and the other day, were negative. I'm so confused😕. I have an appointment on Monday, but I still don't know what to really do. Any advice?
