Waiting for a positive...

Melissa
Wondering if I am jumping the gun here...
Had a natural miscarriage at the beginning of November. And then AF returned December 7th. According to home ovulation predictors, they were positive on 12/23 and 12/24.  According to the app my AF should be returning tomorrow or Thursday (I'm not always regular to the day), but so far only negative tests... Am I testing too early? I'm nauseous,  my boobs hurt and I am exhausted!
Thanks in advance 😊
