I’m scared to report my marriage to Covered California because I’m pregnant and give birth in 6 weeks and will no longer qualify

Please help!! I have Medi-Cal through Covered California, and I got married on May 19th. My husband makes enough money where I would no longer qualify for free health insurance. Covered California requires marriage and income changes be made within 30 days. It's been 29 days now since marriage and I'm so scared to report the change because I'm almost 8 months pregnant. I give birth in 6 weeks on July 26th, and I NEED to be covered. I cannot pay out of pocket. This was so last minute because none of this dawned on me until a week ago. I have absolutely no interest in committing insurance fraud. Is there a grace period where I will remain covered if I go report the change tomorrow (June 18th)? My husband's insurance plan (with me included) doesn't start until August 1st, AFTER our baby will be born. So I'm just in a predicament and I'm scared…!!
