What should I do?

I have been married for a year and a half and its been the best time of my life!! But now I’m ready to TTC and my husband was okay with TTC in December so we tried twice but with no luck. He told me that if it didn’t happen in December we could try again in January well that time rolls around and now he’s decided he doesn’t want to TTC. Last night we had unprotected and was in the moment on my ovulation day. He asked me afterwards if it was a “blue” week and I told him yes and he got upset because I didn’t tell him. What should I do? I honestly wasn’t thinking about that in the moment.
