Confused

My husband and I are trying for our second child. As exciting as it is I’ve realized it’s also a bit frustrating. I took a pregnancy test a week after my missed period and got a negative result so I decided to wait until my period started thinking it was just late. But now my period is 18 days late! And I have no cramps and no spotting/bleeding. I’m not sure what to do? Is there a chance it was just too early to test? Should I go to the doctors or wait a couple more weeks?
