Question about maternity leave

Nina • March 4th, 2016❤️
So I'm a first time mom. I am 26 weeks pregnant. I have always believed that you don't go on maternity leave until after you have the baby (if you are healthy enough). But now people are telling me my doc will take me off at 32 weeks? I am a veterinary technician so it requires a lot of mobility. Any words of wisdom? Thanks in advance.
