When should I talk to my daughter about birth control and how

Anyone who has followed my post knows me and my husband found out our 15 year old daughter was pregnant when he found a pregnancy test in the trash. We talked to her after school and she started crying. My husband did a way better job at comforting her than I did. I'm just not good at saying the right things. She had sex with our neighbors son Wyatt. They both lost their virginity to each other but she says she thinks they put the condom on backwards and during sex it fell off inside. She did tell him she was pregnant and he was ready to drop out of school to get a job at hia uncle's farm a raise the baby lol. We all had a meeting with him and his mom. I made it clear nobody was dropping out to live on a fame, but it all went very well. Wyatt is a very respectful kid. He just always kept to himself which is why I was surprised that he is who she ended up sleeping with. Sadly her pregnancy ended up being ectopic. We found out when she was screaming in pain. She lost a fallopian tube and could have DIED! Shes been really depresses since then. Wyatt has come by and they stay in the living room. He bought her some candy ans his favorite books. According to her they are just friends. She just wanted to lose ger virginity to someone who was also a virgin. Still yet I think we need to have the birth control talk. But she's still extremely depressed about what happened and I dint want to come off as insensitive. Her father(my hubby) was always the better one at making her feel better because he knows what to say and how to comfort. Its been over a month since the ectopic pregnancy. Should I talk about it now and how?
