Period doesn't seem to be arriving??

I had protected sex with a condom on Day 20 of my cycle, the day I assumed I ovulated because I noticed egg white CM although <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> predicted it to be day 17. Predicted period for day 17 ovulation is day 30. It's day 35 now and I'm still not seeing my period? My PMS symptoms started to show since day 31, but it gradually subsided and today I'm not experiencing sore boobs like the last few days. Slight cramps here and there, no spotting, CM is dry/ sticky in small amounts, cervix is relatively low, soft and open. I get irritated easily. The guy didn't ejaculate into me, and the condom didn't break. Do you think I'm pregnant or I'm just stressing myself?
