Feeling unsure this cycle, any words of encouragement?

I'm pretty sure we bd at the fertile times during this cycle because i noticed ewcm for two day then we bd on those days. Then one more time after that. If I go by ovulation calculators it says I should be in my fertile time, but now fertile cm or ov pains and cervix feels more closed now. So I feel so unsure if we timed it right, think ov came early. Trying to stay positive but it's tough! Two Questions which is better at predicting ovulation the cervical mucus or opk tests and to the ttc ladies out there what helps you stay positive during the ttw??? Thank you for all your answers:) Hope this is our month!
