Has anyone just not lost any weight at all?

I’m ending my third full month, so I’m up to 1mg. I haven’t lost a single pound. Currently 164f, 5’5”. 51yo. I’m not an over eater, before starting the meds I averaged about 1500 calories a day, and if I went off track eating too many carbs or whatever I would start gaining. I was hoping this would help me reduce my calorie intake a bit, but I still feel hunger several times a day, although I do find it easier to stop half way through some meals. I’m starting to incorporate exercise. Just wondering if anyone else has had this experience
