Do any women here agree that fasting is more difficult the week of your period?

It’s so easy for me to fast 20:4 all the way up to the week of my period, then it gets a little difficult to stick to the schedule. Just wondering if any other woman noticed this aswell. via /r/intermittentfasting https://ift.tt/f3gsq7S https://ift.tt/5JxEtpu
