when would you test??

hi all,  not been on here for literally ages. 

just after some opinions really. we are currently trying ( allbeit not very actively) for number 2. 

when i had our first i came off the pill and more or less exactly 4 weeks later i had first af. think probably 4 weeks 2 days or something. now this time i have already been off for 5 weeks 1 day. i think we bd at right ish time but we really arent puuting too much effort in at the mo.  so my questions are for those on your 2 nd did it take the dame amount of time for af to come back 2nd time or should i tghink about testing soon?
