Missed two days lamotrigine—what should I do?

Just realized while at work that I’ve forgotten my Lamictal for 2 days. I’ve never missed more than a single dose before and I’m panicking a bit— I’ve felt a bit wonky the past two days but just thought I was coming down with something. I know they say after 3 days you need to retitrate— am I ok just taking my normal dose tonight?
