help?

I'm 36 days late, 48 dpo, no sign of period anywhere. Last period was April 24th-29th, I haven't had one since. I ovulated May 6th, and ofcourse tried conceiving. My period has been regular for the past few years until now. Negative hpt. Around the time my period was supposed to come, there was white/clearish discharge. 
I'm just really frustrated because I'm not getting any answers. 
I don't have a doctors appointment until July 6th...
