Natural miscarriage 💔

I’m Christian and I understand the whole Gods will be done so please don’t comment anything negative. I just had my son in March and I just found out that I was pregnant again. I’m 10 weeks and 3 days. I don’t have a car, my now ex boyfriend kicked me out of our apartment so I have no where to go. He wants nothing to do with this baby. His mom suggested I get an abortion that I can’t afford. I caught him cheating in our bed. He fought me and called me a bitch and everything. I really can’t deal with another baby right now. I know it sounds selfish but I just can’t. Not emotionally, physically, or mentally. Can anyone tell me how the vitamin C works to induce a natural miscarriage?
