My friend needs help


Hey, so my friend is 16 and has a boyfriend. They have a lot of sex but do not use birth control!!!?? She's about 2 weeks late currently but won't take a pregnancy test because she is scared? She has brown skin and recently noticed she has white bumps on her nipples and her boobs are getting bigger. Do you think she's pregnant? What can I do? I know it's normal for teens when the periods aren't regular but she's been regular on her period for years
