How would society be different if humans possessed a heat cycle?

Primate evolution has led to the loss of a heat cycle. This has allowed us to have children at any time of the year. But imagine a world where humans never gained that ability, perhaps even evolving more effective heat cycle depending on climate, temperature and environmental pressures.

Human culture is very intertwined with mating. It's difficult to conceive of a world where people could only become pregnant at certain times a year. I imagine that a civilized society would still have sex during other times of the year but we would not be able to conceive.

But I'm wondering more about the larger impacts in a society without the ability to breed for most of the year. What new businesses would appear? Why would they be successful. Assume that this kind of reproduction rate is sufficient for most environments on earth, allowing humans to maintain a stable number.

What would the major, most notable, differences in a world where humans have a heat cycle?
