Ladies who’ve had a Hysterectomy but kept their ovaries...

I had a partial hysterectomy in December and noticed that I’ve put on 7lbs even though I have not changed anything about the way I eat or exercise. I eat pretty healthy and only indulge here and there and I walk about 1.5 miles everyday day. I have done this for about 3 years and managed to maintain my weight. I’m only 5’2” and 7lbs May not seem like a lot but it is when you’re short. I’m 39 years old and know it’s harder to lose weight with age but I was just curious if anyone else has experienced this. The internet hasn’t provided anything conclusive and my dr says my weight is fine. I’ve been 134 consistently for the last 5 years and now I’m fluctuating between 140-142. Thanks in advance! 💚🙏🏻
