Pregnant but testing negative?

Diana

I have sore itchy boobs with pain that comes and goes, lower back pain, peeing more often and hungrier than usual. Also I get belly button pain sometimes? I believe I am over a week late but my period is irregular and if I am pregnant I would have conceived December 27th. Possibly testing too early? I know these could be pms symptoms but they have started days ago and I don’t usually have these for pms I only get mild cramps.
