Missed my LH surge???

Laura
I'm confused ... Is it possible to have missed the LH surge? Has this happened to anyone? I'm on day 16 of cycle, I use clearblue digital and have been testing since day 10, last month I ovulated on day 13... Ive had no smiley face so far this cycle.
We've BD a lot as you can see around the times I thought I would be fertile. So now Glow keeps pushing out my Fertile days and next period due date. 
Any suggestions? Keep testing for ovulation? Keep BD? Have I missed the surge and already ovulated? I don't want to miss my window and give up now.... But trying to get my hubby to BD and not feel like a chore is getting hard!! 
TTC for three months and it feels like EVERYONE around me is pregnant right now or announcing they are pregnant and it's hard!!!! 
Any help or advice would be very much appreciated :)
