Thinking I'm pregnant

Khristmas
So I'm now five days late period was supposed to start on the 7th of December ... I took a test after being three days late got a negative result... ive been having slight cramping like my period is about to start and nothing... I also remember spotting a week before my period was supposed to start it lasted for two days I wore a pantie liner... My boob's don't hurt but my nipples seem darker than usual... I don't have a appetite for real food just ice cream and sweet stuff... I poop a lot more than usual but when I do there's a little struggle but nothing serious like constipation... I'll get nauseous every now and then... My period pad said I'm supposed to have a period on the 23rd of December... Do you think I should wait for that one before taking another test or just wait for a few more days!?
