pp sex and pregnancy

I was a ftm. I experienced infant loss on 10/26. Induced with my son with no epidural and he only lived for about 15 minutes after an easy pregnancy, labor, and delivery.

Recovery has been good despite not having my baby here with me. Only cramped for a few days after birth, stopped bleeding 2 weeks pp, the hardest part is pumping with no intentions on feeding a baby.

My fiancé and I had sex Sunday. Please don’t come lecturing. I understand the possibility for infection which is why this only happened once. We’ve been grieving and just trying to cope. This was an in the moment thing.

Part of us want to conceive right away as we feel like parenthood has been stolen from us. Since we had sex I’ve been feeling exactly how I felt in early pregnancy but I know it’s way too soon for pregnancy symptoms. I’ve been mildly crampy and gassy. Could I already be pregnant again? Could I have ovulated this soon?
