Yes you can go, the only thing is that your AP applications will be invalidated, which means you will need to come back and apply that again.
I don't know which Service center are you in, but in CSC they are already proecessing for 03/29, which means the case should be ready for approval. Else just go and spend the money again.
I don't know what happens to the EAD application...
P.S: This is not a legal advice, Iam just a lay man like you, use ur judgement.
