my period is 2 days late

Nicola
So my period is 2 days late. I have had cramps for the last 4 days on and off. I also have tender nipples and my gums have began to bleed a bit when I brush my teeth.   I googled this and these are early pregnancy signs. Do you think I should wait a bit longer or do a test. Anybody else had bleeding gums at the beginning.
