With my son I didn’t have this issue, it’s seemed since I found out I am pregnant I’ve had canker sore’s after canker sores.! First one on my inner bottom lip, after it went away days later one on each side of my tongue, they went away and now I have one forming on the crease of my gum and lip and it’s driving me crazy!!! Is this a pregnancy thing?! If so what exactly is causing it and how can I prevent them / get rid of them faster? I’ve always got canker sores a few times a year since I was a child but this is 3-4 sores within a month which is insane.
