Heartbroken after miscarriage

I️ got pregnant for the first time and my baby miscarried at 7 weeks and this was 4 days ago. I’m so sad. This was an accidental pregnancy but after losing this baby I️ feel determined to get pregnant again even tho my bf doesn’t want to try or won’t agree to it. But he was okay with me being pregnant when I was. I️ just don’t understand life and would it be horrible if I️ tried to get pregnant in s few months?
