Getting married and need a good diet exercise plan

Soooo we kinda jumped the gun and decided that we couldn’t wait to get married, and didn’t wanna wait to plan a wedding to my liking so we’re going to the court house April 5th and having a typical wedding later down the road, and I wanna lose a little weight. I’m not asking for a miracle here, I just wanna look good in the pictures and I need something thatsbeffective but not to hard to keep up with since I work 5 days 14+ hr shifts, nights. So I’m usually sleeping during the day.
