Im confused any advice

Ive been trying to track my ovulation again but i dont know whats going on the 5th my cervix felt kind of high and soft and i had a bit of eggwhite discharge like just alittle bit and bbt was 98.84, but i took a ovulation test and it had like 4 lines on it when its supposed to have two. I havent been able to buy more yet, but the next day my cervix was low and soft with watery discharge and my bbt was 99.12. And the day after it was REALLY high and soft with tons of watery discharge, but my bbt was 98.82 and today i checked again, my cervix was kind of low and soft with lots of watery discharge and my bbt was 98.81. And i check my bbt first then my cervix. Does anyone else's shift Every day?? Is this normal?? Ive never noticed mine doing this when i checked it in the past, but then again i only checked it for around a month and everytime i felt it was pretty hard and low
