Asking for a friend !

Breean • Mama to Delilah Mae Dexter Kash and Declan Grey 💖
I have a friend who has just found out she is pregnant her last period was April 20th for 4 or 5 days and the guy she "thinks got her pregnant" she had sex with on May 7th and a different guy she said 3 weeks later . Would it be the second guys baby or the first !?
Short story of why I am curious:
She is 20 years old and the first guy she had sex with has only just turned 17 in February and her aunt is a school councilor and she's a mandatory reporter person . And my friend is living with her aunt and she is trying to force her to get an abortion before she turns her in for sleeping with a underage boy ! Any input would be so appreciated !!!!
