Period lost after introducing Intermittent Fasting

I have introduced intermittent fasting to my diet since I want to lose some pounds. Unfortunately, my cycle changed since then and I have not received my period since April 2022. I am really a bit worried because I think it may be due to the fasting.

So what is your suggestion? Should I continue and see what happens or should I stop? I see my gynecologist in mid-August to have a hormonal check-up.
