Sex after moving in?

It feels like since my boyfriend and I moved into our house a few months ago sex dropped off significantly. We were ttc , but decided to stop recently for now..but since September it seems like the only time we were having sex was during fertile times and even then it was maybe two of the days if I got lucky. It makes me feel insecure like he's not happy anymore or no longer attracted to me.. He says that's not the case but won't really give me a for sure answer either. Idk what to do. Is this normal?
