I need some help..

I think I've hit my first plateau. A little back story. I started my journey in January of this year. Lost 20 pounds from then until May. In May, I had my wisdom teeth extracted and was on liquids and soft foods for about a week and half. I lost a pound during that time. I ate a little more than I should have after I could eat again, that lasted about 2 weeks, but got back on track with exercise and eating at my calorie goal. Mfp originally had me at 1700 then 1600 calories a day and I consistently lost a pound a week like I was supposed to. After I got back on track, mfp had me down to 1500, but I have been at the same weight since May. I measure and weigh all my food, I switched up my exercise from treadmill only to a 30 minute hiit exercise to see if that would help and I exercise at least 4 times a week. I've been pretty much eating the same foods as I was, because I'm a picky eater. I still have not lost the weight I was losing at a higher calorie intake. I'm 5'4" and currently 194lbs and started at 216. I guess I'm wondering if I should add some calories back, or keep going like I am. I'd like to see the scale start moving again.
