OPT expires in 15 days and H1 in process,what should I do?

Hi ,

My OPT will expires within 15 days this month. My husband is my dependant.

My H1b is in process , I do not get job but my consulting company had file H1 for me.

I have applied extension for OPT in my DSO on basis of H1 Reciept , it is still in process.

I am still searching job.

Now my question is what are the possible options for me if my H1 denies?

How many days I have left after it denies and what I can do between those days?
