Pregnant or not????

So, I know everyone is different, and it’s been 8 years since I’ve been pregnant, so I’m fuzzy on the early details. I missed my period. I’m 5 days late now. I’m literally never late, always on time or a little early. I took one test at the beginning of the week on my due date and it was negative. I just took one again tonight(I work night shift), still negative. I don’t have my usual signs of my period coming, but I’m seeing a lot of people get positive tests as soon as their due date or 10 DPO. Should I call my OB and skip right to a blood test to find out? The suspense is killing me, but if I missed my period for a different reason I want to know sooner than later as well.
