Hey Rose! I usually break a plateau myself by either picking one day and eating to my calorie limit. Or, I do 15 minutes extra cardio at the gym for a week.
Also make sure to drink 8+ glasses of water a day and keep low on salty foods and you will be able to see yourself break that plateau.
How long have you been stuck at those weights? For me I sometimes go a week yo-yo'ing but it will eventually come off the second week
