AF was due Dec. 31, but...

I took a test a few days ago, but it came back negative. I have my cycles down to a science, so missing AF is major for me 😬 (since we are currently TTC for my last three of four cycles), but I just don't know what to think right now.  Symptoms I have had the last few weeks are indigestion, EXTREME fatigue, very sore/sensitive breasts and nipples, mid&lower back pain, slight nausea, and minor mood swings. Should I test again tomorrow (Jan 3)? Or wait a few more days? PLEASE HELP! 😩
