Confused and sad

Literally been TTC 6 months, my SO was excited and ready, now yesterday SO says we aren’t ready.... I feel as if he’s discouraged and giving up. So I told SO I’ll get back on BC he got upset . Well I’m upset to and confused , we still BD and he knows today is my Ovulation PEAK DAY...

I’m not so excited about a baby anymore after he said that..

Should I go and get birth control and not tell him?
