Ques about timing?

here it goes....i got my period on may 15th and i've been using the clearblue fertility monitor and on the 25th(CD10) and 26th (CD11) i got a "High"...2 bars.......hubby and i did the BD on the 23rd, and 25th. then on the 27th & 28th (CD 12 and CD 13) the monitor gave me a "Peak" 3 bars w/the egg symbol....hubby and i BD on the 27th & 28th. ...but then on the 29th (CD14) the monitor went back down to just a "High" 2 bars. w/that said i was just wondering if my hubby and i got our timing right.....today the 30th (CD 15) the monitor went back down to a "low" reading, just one bar. and i've also noticed some CM being milky and lotion like....but not alot just very little and i never saw the EWCM....i'm just wondering if its gonna happen this cycle.....hubby and i have been trying for baby #2 for 4 months now.
