Well you cant get pregnant through your belly button but the "pull out" method is not at all effective...You can still get pregnant from what they call pre cum it comes out at the beginning of sex...I would get on birth control

Ya you can't get pregnant through your bellybutton, but you can get pregnant from pre-cum.

can u get pregnet if the guy cums on ur vagina twice??

you can if it is close to the vag opening. Sperm swim.
Use condom or pills...better yet, use both. STDs are not stopped by pills
