Pregnancy at a young age advice

Hi everyone. I found out a few days ago that I’m pregnant. I’m only 19 and it’s a huge shock not planned as I was on BC.. the father wants a termination but I’m still in 2 minds I feel close to it even though it’s only a little bean... has anyone had a baby young? And could give me some advice? Thank you :) I’m only approx 5 weeks I haven’t had a scan yet
