Bedroom problems, help~~

Hey girls I need your advice on how to make my sex life better. My husband is 9 years senior of my age, I am currently 33. We’ve been trying to TTC for the past 2 months, It wasn’t great for the past month. After 4 years of marriage, we love each other more now but the bedroom part has gradually becoming difficult. Last night he told me he wanted to go to bed at 10, (which we usually go to bed at 12-1am. ) I was excited cuz I thought he initiated going to the bedroom and we can have some fun. At the end he was like I really was just going to bed. I awkwardly admitted that I misunderstood the whole situation and I was very disappointed. We have previously discussed that we will skip the opk and just go with the flow naturally , and he was the one suggested that we can try once every two day. However when I try to get intimate with him and he was like” are you ovulating today? I was like I thought you don’t want me to use OPKs or bbt and we just go with the flow. The most important thing is why can’t we have sex even I am not ovulating. At the end of the night, we were very upset with each other. My heart is tired… I don’t even know how we can conceive a baby like this. In worst case I am not sure if I should have baby with him anymore. Help girls!!!
