I was wondering if any other girls on lamictal have had this...

I've been on lamictal since september this year, i started on 25mg & slowly uppedyself under doctors orders to 75mg with no dramas

When i went back to my psych, he upped the dosage to 100mg & i was also put on stelazine for rage that i seem to have no control over & feel like its tearing me apart!

Anyway, since ive been on 100mg of lamictal, i have not had my period yet...i havent had one in over 2 months now & am just wondering if this has happened to anyone else?? =\ it happenend last year when a doc changed my contraceptive pill but i changed back over to my original after 2 months & no sign of a period...eversince everythings been fine & normal but now since the upped dosage i seem to be experiencing it again...does anyone know if lamictal can cancel out the contraceptive pill by any chance?
