Medi cal coverage on my pregnancy pills?

So i got medi cal for myself and my baby. And im 24 weeks and switched doctors but my doctor prescribed me prenatals, iron and calcium..and the calcium didnt cover for some reason so i have to pay $10 out of pocket. 😳 before getting this doctor i just paid for my own prenatals at the rite aide store and used one a day prenatals. Now im going to take prenatals prescription and im kinda scared to switch to those idk why. Will i be ok???? 😕 will the baby be ok? I hope these dont harm me and the baby. And also make me throw up. Because i was fine with the one a day ones. And also why didnt the calcium pill cover with my insurance?🤦🏻‍♀️
