Should I test or wait a little longer

So per the calendar I ovulated the 16th but per Clearblue digital I actually ovulated the 20th. Every month I get my period per these calendars right on the dot. But since I actually ovulated later should I take a pregnancy test or wait since I am right around that 2 weeks since the clearblue test came back High. Back story had a failed IVF back in June (was trying and then had some scans that showed masses on My ovaries so we thought go through IVF and then we can implant at a later date but only got 1 embryo) doctors say everything is good on my end and SO end also so they say to just keep peeing on sticks and trying.
