To test or not to test...

Hi guys, so I've been tracking myself a while now and showed most fertile last week. Me and the hubby have regular sex anyway but just made sure on the important days that we did :-) anyway, I am wondering if a week after the most fertile date is too soon to take a pregnancy test as I've looked online and a lot of forums say wait until your period is due but I'm 2 weeks away from that yet.... all advise welcome :-) xx
