What I should do

Valerie
Hi everyone!! I have a irregular period, this one suppose to came at June 28 today is July 1, 4 days after my period suppose to come. I went to the gyno yesterday and she gave me a exam to see If I am pregnant but my husband said why I do not wait for my period to come?
​The issue is that all the pregnancy text that I did, negative. What I should do? Wait or do the exam?
