SO or DH?

I just don't want to feel like the only one. But SO and I have discussed actually trying for a baby and I recommended that we bd every other day (we usually only bd maybe 4 times a month otherwise) but the other night he was laying there and I asked him what's wrong and he said are we gonna do this? I told him from the beginning I didn't want it to seem like a chore to ruin our relationship and he is all for having a baby. But I just feel like it's a chore in some way. he works long days and I work nights with occasional nights off (service industry😥) does anyone else SO or DH make it feel the same way even though they want babies to and were just trying to make it happen lol? we've been together almost 4 years now..
