Did we BD enough ?

D

This is the 7th round and hoping to get an positive test after my 2 weeks wait. I am curious if we did BD enough. I will leave down here my calender and my OPK test results and like to hear what you guys think!

Time we had intercourse:

July 13 about 23:30

July 15 about 13:00

July 16-17 about 01:00

July 17-18 about 04:00
