Possibly Pregnant? Help?

A couple weeks ago my boyfriend and I had unprotected sex and he cam inside of me (was planned). It was 3-4 days after ovulation though. I was supposed to get my period 01/13 and now I’m 5 days late. I’ve taken two tests and both were negative. Was I too early to test? I have a doctors appointment tomorrow, should I ask for a blood test? Kinda new to this stuff, any info helps thanks :)
