Prozac plus progesterone and a scale that keeps creeping

I’m not looking for medical advice, just comparing notes with people who track their own patterns. I’ve been on Prozac since winter, and a progesterone pill was added this spring. Mood-wise, I actually feel more like myself. But my weight is up about nine pounds over roughly eleven weeks, and I can’t explain it from my habits alone. My breakfast and packed lunch are almost identical, my step count hasn’t dropped, and I’m sleeping about the same. The confusing part is my hunger feels less predictable: some afternoons I forget food entirely, then evenings feel ravenous. I’m cautious about blaming the meds by themselves because stress and sleep have shifted too. Has anyone else noticed a slow creep with either of these, and did tracking anything besides calories help you understand what was happening? I’d also welcome gentle ideas for what to ask my prescriber.
