Positive? Help!

Hi! So the other day I did multiples test because I missed my period and wasn’t feeling so well. Anyways it showed a fainttt line in the 3 minutes wait and I’m freaking out a bit. I really wanna make it and have this baby but the problem is that i’m only 20 years old I’m still a student with a part time job and living with my boyfriend parents.. I’ve talked about it to my mom and she’s super supportive so that is not an issue but I’m scared that it will ruin my 3 years relationship with my boyfriend and do this alone because he isn’t ready.. I have so many thoughts going on in my mind so I really don’t know what to do.. can someone help me?? Btw I’m sorry English isn’t my first language
