Maternity Insurance for IVF & Twins

Hi, has anyone managed to buy maternity insurance at 13 weeks with twins through IVF? May I know which company you bought from? I’m having twins conceived through IVF and wanted to buy from prudential but then my agent tells me that I can only buy from 28 weeks 🤦🏻‍♀️. Great Eastern doesn’t accept IVF pregnancies. Thank you! #advicepls #firsttimemom #firstbaby
