Anxious about marriage

I got married this past weekend. My husband and I have been together 5 years and i had no nerves leading to the wedding. But once i woke up the next day i started to get this ball of anxiety in my stomach and its been 3 days of not wanting to say husband or talk about the wedding.

Does anyone have any experience with this feeling? We have an almost 1 year old and we’ve been living together for a while. Literally nothing lifestyle based changed.
