So I've been keto for 3 months. I started on a period. Then a month in I got my period on time. So no concerns at this point. Then come the next...It didn't come. In over a decade of periods, I'd never been late, but I waited a week just in case. Still nothing. I'd skipped a period. Figured diet change with calorie restriction (roughly 30% deficit) and weight loss could have caused it and decided to wait and see if the next still hit. Online sites said if you go 2 periods that you should see a doctor.
So the next was due yesterday. Hasn't happened. I'm seeing a doctor tomorrow, booked appointment over a week ago I think since I was concerned regardless.
I also don't really have much libido so maybe not ovulating?

Looking at this site >>https://www.healthline.com/nutrition/low-carb-and-womens-hormones#section2

It states that some women can stop having periods or irregular periods on a very low-carb diet.
Wondering if any other women here experience this.

Should I go to moderate carb (about 100g total) or maybe have a cheat day each month where I eat over 200g total carbs to rebalance? I currently do <20g net which is <50g total.
I like keto. It makes me feel good and energised. I look and feel so much healthier. This is the only issue I'm really having. I'd prefer the cheat day over switching to moderate if it's plausible.

I'll let you know how the doctors goes and blood results when I get them. I'm also going to a gynaecologist in a weeks time, for the first time (never got around to it, been too afraid).

And just so you all know, I've never been sexually active so 0% chance of pregnant. I'm 24 so not menopause.
