Pregnant and Have a cat

Hello. I'm 13 weeks pregnant. We have a 4 year old cat and there's no way am I giving up my cat. My cat poops and pees in the garden outside and has never had any accidents inside.. Just sometimes they do bring in a dead squirrel. They don't jump on furniture due to training and we've had him since he was a kitten. We do bring him to bed sometimes as he's such a cuddler but he waits for us to put him on the bed. He doesn't take out his claws or scratch or bite. Maybe only if I'm showering him but recently we've been able to afford a groomer so that's no issue. I'm wondering if there's anything I need to prepare prior to the baby coming.
