Body changes during periods?

Is it just me or I feel my body changes in like one day, the first day of periods??

Not in a good way of course 🙃

I feel fatter, shorter, my skin is dryer and have some skin scars and cellulite I hate that so much :(

Don't know if it's real or just my imagination lol

Everything seems more noticeable 😭

Do you have that too?
