how do I balance being pregnant and a full time college student?

I'm 6 and a half weeks pregnant and I've known since I was 3 1/2 weeks. My hubs and I were trying for almost a year so I'm sure you ladies know the excitement of finally getting a BFP! I graduate from a university in May with my bachelors so I'm currently taking my last semester of classes. I can't focus whatsoever. The baby is all I think about. I have no motivation for school and that is so unlike me. I'm so worried I won't pass a class and won't be able to graduate in May. I just feel so lost and not like myself. I don't know how to balance everything.
