17 yr old Best friend thinks she’s pregnant

Hey everyone

So my best friend has been with her boyfriend since December and she thinks she’s totally in love with him and wants to marry him etc

She told me yesterday she took out the IUD (cos it sent her crazy) and then continued to have unprotected sex after (no pull out or anything).

She’s basically told me she is late for her period & she thinks she is pregnant. She also said to me that she thinks she WANTS a baby anyway, and her boyfriend feels the same.

She has had a hard time the past few years , had to drop out of high school because of her mental health issues n that but She finally is starting to get back on track, getting her GCSEs at a college , and she goes and tells me this

I’m obviously gonna support her no matter what, but she is not in the best place to have a baby. She nor her boyfriend have no job, lives at home with her mum and brother. She told me her mum would help her but there’s no way her mum can support her 2 kids & a grandkid on her wage

I’m at loss of what to do- do I give her advice ?? do I just let her ride this journey and stick by her side? What do I say to her?? Can Any young mums guide me on what to do as they’ve been in the same position??! HELL P
