I would make an appointment with the dentist. Mine told me if I had any issues with my teeth or gums during this pregnancy to give them a call so they can monitor and keep everything healthy.
That's normal for pregnancy. Just make sure you are taking extra care of your teeth. Maybe book a cleaning at the dentist if it's been about a year since your last. Also make sure that you are getting lots of calcium to help your teeth stay strong
Swollen and bleeding gums is normal during pregnancy due to the extra/stronger blood flow in your body.
Let your doctor know and just keep an eye on it incase of any infections :)
