PCOS and weight gain and IVF

I am so very frustrated. I've always had PCOS with symptoms like weight fluctuation, insulin resistance loads of hair everywhere. With diet and exercise I used to be able to keep the weight at 62-64 kg (normal BMI)

Ever since IVF I've been putting on the weight though and it's Not coming off. I'm fairly active, I do a min of 10,000 steps a day, I either go gym or do yoga at least 4-5 times a week. I eat SUPER healthy, no sugar, nothing processed, gluten free, whole grain, 3 times a day no snacks and normal to smaller portions. Honestly nothing I am putting into my mouth should actually be the reason why I am putting on weight. It's so frustrating because my clothes are tight and I simply don't feel well in my skin. I got pimples around my face 😭😭😭😭. What else can I do ? Someone please, has this happened to you? What did u do? I'm so very frustrated and upset.
