Should I take another pregnancy test?

So.. I stopped taking my BC pills about March 17th. My last period came on March 2. When I stopped taking the pills, I did have some breakthrough bleeding. My next period (which should have been abt March 29th) never came. I took a pregnancy test two days after the missed period.. and it was negative. Should I take another test - that was over a week ago. Or should I just wait for my next period. My hubby and I have had unprotected .
