Full time student? 2 part time jobs? And pregnant? Too much??

Eva • My husband and I have a son who is 3 (10/5/15) and a daughter who is 1 (11/30/18) and we just found out we are expecting again!
I am currently enrolled as a full time student and I have 2 part time jobs (I work everyday for at least 5 hours) and I found out almost a week ago that I am pregnant :) I am so happy about being pregnant but is it bad that I feel like I can't handle school right now too? That I want to stop for now (I already plan on going back). I just feel like I need to focus on baby and work
