All pregnancy symptoms but test is negative:(

My period is late for 3 days. From yesterday evening I’m feeling all pregnancy symptoms: cramping, nausea, fatigue , dizziness... Everything that I was feeling 6 months ago when I was pregnant but unfortunately on my 6 weeks I got a miscarriage. Two pregnancy tests are showing negative 😭😭😭 Maybe someone knows what it can be.. I made an appointment with my doctor on Monday but I’m really worried and can’t wait till Monday. Thank you!!!
