pregnant for the second time at 19!

Hi mamas, i have a beautiful 2 year old daughter. things went left with her father about 2 months after she was born. i am with a new guy now, we’ve been together about a year and half. I just found out yesterday i am pregnant. based off my last period i’m 10 weeks, 6 days! i made a gyno appointment for friday. i’m just nervous. i know i can handle this, but i am super scared that i am having a baby with another guy who isn’t ready! i really don’t think it has even hit him fully yet at all. and it’s just sticky situation. we don’t live together & i live with my mom, and it’s a pretty small house, i know i want this baby i am just so nervous. this might be super long and not even make much sense but i’m just looking for a peace of mind. i have 1,0000 thoughts flying around my brain at once😩
