Am I over reacting?

My fiancé and I have been together for almost 2 years and I really want a baby. He knows this and feels the same I guess but it hasn't been easy. We've been trying for months and it hasn't happened for us yet... so obviously I track my ovulation very closely. I told him this is my ovulation week and tonight would be the perfect night to have sex for hopefully the results we've been wanting.

Around 8 I start watching bachelor in paradise, he lays next to me and says "I'm going to rest my eyes while you watch your show, wake me up when it's over so we can have sex" I said okay great. Time comes, I wake him up, "babe, it's sex time" and he replies, "ha, you actually believed that?" And a sarcastic "ha ha ha" and goes back to sleep. Idk why but I'm literally in the bathroom bawling. He knows how important this is to me and how I'm struggling. I mean, I thought it was to him to but that just really made me think different. Am I wrong for being upset over it? Because I just want to give up at this point.
