Advice please!?

Hi Ladies,
So I'm on day 30 of a 50 mg days 3-7 cycle. 
I tried to lower my stress and did not BBT this month I did to Opks and I believe my LH surge was day 20. 
We baby danced day 20 and day 22 of was just bad timing...
My first question...did I miss my surge or is it possible I could still conceive?
Secondly, when should I test, I took one this morning and it was negative. I don't want to lose hope, but it's hard. 
Let me know your thoughts, thank you!
