no period symptoms

I've been having some nausea for the past week usually at night and sometimes in the morning. My projected start date is Jan 2nd. I have horrible periods I get symptoms a week before I start every single time and this month I've had none. I'm ttc. The only slight pain I've had is a ping where my ovarie was but that was 2 weeks ago. I really hope I'm pregnant. I plan on testing the day before the 2nd and after if I'm late. I just don't feel myself the past few weeks. I've had horrible heart burn every time I eat and I never have that.
