Requirement to go to police station after expiry of 90 days

Namaste everyone, A person had filed a section 420 on us. Police filed a FIR and we got a anticipatory bail. Police informed us that we have to come to the station on 15th and 30th of every month and put a signature. I have read that Investigation officer has 90 days to investigate and submit the evidence to court or file a B-report. Our 90 days of signature is over, my question is do we still need to go to the station for signing or wait for the court send us a notice or should we go with a lawyer and ask what is the status of the case? On a side note: They have claimed 6 times of the amount we are supposed to give and don't have any evidence to back their claims.
