So confused, PLEASE HELP!

Dee • We first conceived in March of 2014. We were so EXCITED, we lost our baby & have been trying every since. This struggle has been devastating. Hope we conceive soon ;)
CD21, pos LH surge on June 21st, you can clearly see our bd dates, took an opk today, control line appears darker then test line so this means...??? (At least i think its darker but the colors DO look very close to the same)... So have I ovulated or am I ovulating? 
​We had a mc on 3-12-14 & i havent been the same but my AF predictions for AF are spot on. Glow says to wait to take a pg test, but then it says to go ahead & take a pg test. I want to scream!
