H1B -> h4

I had a quick question. I recently decided to take a small break and decided to move to h4(my spouse has a h1b). I had a lawyer file my application(i-539) but we still haven't received the notice of receipt. Our application has definitely reached the USCIS(from UPS tracking). It's been more than 2 weeks now and my grace period has expired. Has anyone been in this situation? What should be my next steps? Do I need to leave the country immediately?
