pregnant at 19

After the excruciatingly long two minutes, I looked at my pregnancy test and the lines were clear as day. I couldn't stop shaking and crying as I am so scared. 
I then took a clear blue test that said I'm 3+ weeks which they say on the pamphlet I'm really 5+ weeks. 
The father of this child is 35 years old and I'm not sure he ever really wanted a family (we've never spoken about it but I'm just assuming)
Just thinking about telling him and my family is making me feel like I'll have a panic attack. 
I have no idea where to go from here.. it's just so scary and I know I'm to blame for this but I just thought maybe coming on here to tell my story, I could get some insight from you guys.
