What natural methods can i use to get bigger boobs at home?

No magic solution!: There is no magic solution to change your breast size other than surgery. Breasts come in all sizes and shapes. There is nothing wrong with having smaller breasts, just as there is nothing wrong with having larger ones- it's just what you have. Learning to accept who you are, what you can change and what you can't change, is an important life skill.

You cant: There is no safe way to grow or reduce breasts... Whether with supplements or medications. Augmentation with a plastic surgeon is the only safe way.
