Okay ladies

Heven
I have a military husband. He left for the field last week and will be home Friday which is 2 days away now. I've been keeping track of my OPKs and the last 2 days have been darker than usual (as picture shows) does this mean I'm getting closer to ovulation? Or do my hormones just fluctuate day to day and I won't really know until it's actually positive? I'm hoping it holds off till at least Friday evening :) thanks for all your help!!
