How do you shower when you're on your period?

Sorry if this is an odd question. Growing up, my mother used to tell me to not shower during my period. I never really understood why, I suppose it's because the blood can drop down your legs (we don't use bathtubs). But it still felt weird and disgusting.

I make do by rubbing soap and water where I can. I can't take a ' bath tub' bath because, like I said, we don't have a bath tub. I don't know how to properly take a full shower on my period (with my pad off) because I fear the blood will drip down on the floor, and we live in a small house so about 2 other people use the same bathroom, so I feel more hesitant. I'm scared of tampons, so I don't think that's an option either.

I feel super embarrassed to ask this ngl, but if you have any advice then I'd greatly appreciate it!

Edit: I've read all the comments I've gotten thus far, and replied to a few too. Thank you so so so much for the advice!! I think I was a bit too paranoid about not listening to my mother, but the comments have helped tonnes. I'll try the tips out!

I'm glad that the tips are mainly the same across the replies. I truly hope this helps out any other lady with the same question as me.

Once again, thank you for your kind help and advice! ❣️
