Pregnant by fwb

Three weeks ago I took a hpt and discovered that I'm preggers by my bang buddy. I was in shock, denial and now remorse. Remorse because I haven't told the daddy. (I haven't told anyone.) I was thinking of waiting until my 8 week appt to confirm before worrying him. Let's face it, the home test confirmed it, I'm just scared to tell him. So, I decided to reach out to him today to "talk"...so far, no response from him. I don't want to tell him via text, so, I guess I'll continue waiting... hopefully, I can tell him before this weekend. If not, 8 weeks isn't too late to tell him, right?
