Would they pick up my HCG levels on a blood test?

Hi guys! So I ovulate very irregularly and I’m sure that the predicted ovulation dates on this app are not always correct for me. Anyways, I had sex in the 7th and the 16th. Do you think my HCG levels would be somewhat raised at this point if I conceived on one of those days? My doctor ordered an HCG test (getting tested for something completely different but he added that in for some reason) I’m just not sure if it would even show up just yet if I was pregnant. My period is due in 7 days.
