Any females out there have full blown seizures that DO NOT have epilepsy and have found some answers?

I have recently had 4 tonic/clonic seizures in a row and have not been diagnosed with epilepsy. I don't know what caused it and wondered if anyone has had a similar experience and actually found out why this happened. I've heard PCOS could be connected. Can anyone help? I'm a Mum of an 11 month old and scared to death.
