Help !!! Need advice


So found out I'm 5 weeks pregnant yesterday, I'm 25 & my boyfriend is 26 we are by no means very young but it wasn't something I planned and I haven't told him yet ☹️ I'm so overwhelmed with thinking about what I should say as we have jobs but not exactly the best jobs in the world and if I can afford a baby😔 I love my baby already and by no means will give that up but my partner has all these ambitions and I just feel il test his world down with the news 😢 we been together 8 years so it's not like we're new to being together but I just feel a baby is a lot to take on and I don't even know where to start
