Stopped lamotrigine, seizure-free so far. long-term relapse risk?

I have focal epilepsy (right temporal lobe with MTS). I had catamenial focal seizures for years (clusters around periods/ovulation). I was on lamotrigine, became seizure-free, then stopped it about 4–5 months ago without medical review. I’ve remained seizure-free since stopping and my hormonal pattern seems improved. I’m trying to understand the risk of staying off medication long-term and what relapse experience looks like in similar cases (including pregnancy experiences if relevant).
