In dilemma for my last ttc cycle for this year...

Evaki • Ttc #1 at 35

My fertile window is in about 1 week, i ovulate at specific cd.. My dilemma is should i track or should i let it as it is? We are goig to be on vacations for the week, so im thinking should i relax, or should i use opk to track? We are going for vaccine after that ttc month, so based on our docs we are going to ttc again from December probably..
