15 and was pregnant(not me)

I was sitting at a restaurant with my 15 year old niece. We got on the subject of eating chocolate, then periods, then boyfriends. She tells me she hasn’t had her period in months but that she has the nexplanon implant. I assured that it was normal since I had one myself. I asked her if she considered the iud. She declined because she didn’t want to be asleep when “ they put it in”. I was confused because they don’t usually put you to sleep. She cleared up my confusion by explaining that she had an abortion and at the same one they put the implant. She also later revealed that she was pregnant for a month before she found out and decided to go through with it. I assured her that I would never judge her and I support her choice because she is too young. I was a little saddened that she was having unprotected sex at such a young age. But I told her that if she needed anything that she could ask me in private.
