Since the return of my periods after pg and bf-ing I get lots of nasty, sore ulcers in my mouth. Some are red/yellow spots on the roof of my mouth and are sore enough to effect eating/drinking and also make my glands swell a bit. They arrive with my (very heavy) periods and gradually go over the week.
I presume the cause may be hormonal but can anyone shed any light on why I am getting them and what I could take to prevent them?
