Here are some explanations for behavior:
Emotional crying
The call in estrus is different from the call: the call in estrus is a low, heavy and regular call, which is usually made by the male rabbit when chasing the female rabbit. This estrus behavior can be reduced, but it cannot be completely eliminated. The male rabbit will still chase the female rabbit.

Rabbits may turn in circles when they are adults. Turning in circles is a courtship behavior, and sometimes purrs at the same time. Usually, it's time for rabbits to start courting in circles.
The behavior of male rabbits in estrus is obvious. Male rabbits usually make cooing noises during estrus, but of course they are silent.
Then ride the female rabbit, during which the male rabbit is very active. Every day, if the mother rabbit is in heat, she will cock her tail to mate. If you are not in estrus, you will escape from the male rabbit. And sometimes male rabbits bite the neck of female rabbits when they are in estrus. You can look at the neck of the mother rabbit. If it loses some hair, it may be a match or it just happens that the male rabbit is in heat.
Neck hair loss during childbirth is also very serious.
