20 and pregnant

Someone please give me some advice, I’m desperate. I have found out I am 5 weeks pregnant. I am only 20 and my boyfriend is 23, we have a solid relationship (3 years) and financial situation isn’t a problem. I’m so scared that I’m not ready to have a baby and I feel like everyone my own age will look at me different & judge me. I feel so alone because my friends don’t understand and think I should get a termination because I’ll ruin my life by having a baby. My boyfriend is 50/50 and he will support whatever I decide. I’m worried I haven’t lived enough. What should I do?
