Congratulations on 18 days! Don't worry about being off by a day, I actually thought I hit my 18 month mark in February, only to realize weeks later that it was only 17. The hubs and I even went out to dinner to celebrate my year and a half mark, lol! I let my 18 month mark on the 22nd of this month slip quietly by, seeing that I had already celebrated a month early ☺
