Could it be a 'small' seizure?

Hiya, I hope this doesn't sound too silly! I was diagnosed with epilepsy 12 years ago - i only have tonic clonic seizures, no aura or warning - they're managed by lamotrigine but I've had breakthrough seizures when I was pregnant and when I forgot to take my meds (stupidly).

Today I was in bed just feeling tired and must have fallen asleep. I woke up an hour or so later with blood on my hand and pillow, which has come from me chewing the inside of my cheek quite badly. My immediate thought was a seizure, but I feel normal now. Usually I'm super confused even after the post ictal phase and 'know' I've had one. Also my husband says he can tell fire to how I act. I then am generally very tired and need to sleep, which u believe is quite normal. My question is, is it possible to not have this confusion/tiredness after a seizure if its somehow less severe, whilst still a tonic clonic? Or perhaps I've just bitten my cheek in my sleep and am being paranoid! Sorry for the long post and thank you for reading. Any insight is appreciated. (I'm 40yo female btw)
