Do I still wear a pad if there is no blood on the 1 day of my period

Yes, it is a good idea to wear a pad on the first day of your period even if you don't see blood, because sometimes your period can start super suddenly.

Sometimes you'll get some cramping or feel kinda moody, and then bam, your period starts. But other times, it just shows up without much warning, so wearing a pad can save you from a surprise. It's like having an umbrella ready just in case it rains, even if the sky looks clear.

Also, your period flow changes a lot, especially when you first start getting them. It might be light one minute and then really heavy the next. So even if the first day is super light or almost nothing, it's smart to be prepared. If you're not seeing much, you can always wear a lighter pad or a panty liner, so you're covered but still comfy.
