Welcome to the Wefugees community and thank you for your question.
Unfortunately, it's not unusual that BAMF takes a while to process your asylum application. You have to be patient.
However, you can file an action for failure to act ("Untätigkeitsklage") which forces them to process your case. This makes sense if you've been waiting for a reaction by BAMF for 3 months (or longer). We had a question about a similar topic here on Wefugees in the past. Please check out the information in this thread:
