Mouth Sore

My period ended recently and I tend to have mouth sores around it, however I started Lamictal recently for BP2 (12.5 mg, so, half a tablet) and I got paranoid because then I started developing a mouth sore, it hurts quite a bit but not any more than my usual ones. Can it cause SJS in doses that low? I also got a "rash" near my jaw but it's probably just a bed bug sting, since it's just one singular dot. I started it around 3 days ago so I think it's also too little time for that to happen.

I can't go to the ER because I'm Venezuelan, that says it all. Medical care here is ass, and my family is definitely not taking me to the ER at 11:44pm for a mouth sore. They'd have to pay for a taxi because I'm a cane user (due to EDS) and nobody's awake at these hours. My psychiatrist is probably asleep. Should I be worried or am I just overthinking it?
