Can Hefei maternity social security be filed for more than 4 months?

Yes, I only bought five insurances when I was pregnant for two months. At that time, I thought my maternity insurance was useless, so I didn't get it. When I was five and a half months old, I went to the Second Hospital for examination. The doctor asked me to take the materials to the medical insurance office for questioning, but I didn't expect to do it. Later, I reimbursed 800 yuan for prenatal examination and 5000 yuan for caesarean section. Now I just got my fourth month's maternity allowance, hehe.
