Is it possible to get pregnant 9 days before period if precum got on labia?

No. It's almost an urban myth that exposure to pre-ejaculate fluid can result in conception. This is very rare and only with penile penetration. Don't worry. However, you need to get onto proper contraception; this event was risk free, but obviously you are close to having vaginal sex. I'm aware of cultural limitations in your country, but try to arrange it. At least have condoms handy. Good luck.

No. Sperms have to enter inside the vagina to cause pregnancy. Also precum has no sperms. If you are experimenting or trying sex best is to be on a BC pill to avoid such worries.
