Sorry I’m so late!
First off, congratulations! You’re a woman, and that’s something to be proud of!
Second off, tell your mom, trust me, it’ll make everything better. Or you can tell another woman in your family if you don’t feel comfortable. Some example would be your grandma, your aunt, or an older sister.
Third off, experiment! If pads don’t make you feel comfortable, try something else. For lighter flows, pantiliners are a good choice. Tampons, menstrual cups, or even period underwear might be better for you.
Fourth off, be happy. Lots of women go through this, so being a part of life, you should be happy no matter what!
Hope this helps
