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 :)
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
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.
