H1B Transfer Rejection Options

[Phoenix123456]

I have applied for an H1B transfer. I started working after the receipt notice (when employer filed). I am hoping to receive the an update soon but just wanted to confirm if it gets rejected, what options would I have?
1. Can I convert to H4 asap
2. Can I use my remaining unemployment days (after quitting the previous job and before starting this job, I was unemploed for 45 days)
