Help!!!

My period is two days late. I took a first response test and it was negative. I ovulated the 24th of November and had unprotected sex the whole week. We’ve been trying for months now. I’m trying not to get my hopes up. My period is always on time, even early some months! Could it be too early to detect Hcg?? Should I call for a blood test? Or keep waiting to see if my period comes? Ugh. Opinions please!!!
