Long term hormonal side effects

37F happy to see this supportive community here on egg freezing! Q. is anyone else concerned about the long term hormonal effects of egg freezing? I'm currently deciding whether to do it and I hear from some women how it starts to get hard on their bodies after multiple rounds. That leads me to think that the mega dose of hormones cant be great for the long term and be read a lot on how imbalanced hormones can cause long term chronic illness later down the track. I guess it's hard to know as no long term studies have been done on this front but would be keen to hear from anyone who has knowledge on this.
