Baby dust ?

So I lost my baby in December.. I was 15 weeks. Me and my husband have been having intercourse we try condoms but it doesn’t usually last cause It’s just uncomfortable. Anyways everywhere I go I hear baby, every show I watch it’s a baby or someone getting pregnant or giving birth . Weird things keep popping up on my phone like those pregnancy test add that keep saying “take the test “ . Anyways I was cooking tonight and I found a tiny pepper in a big pepper . I have been feeling nauseous and having acid reflux (which I never ever get) but I feel like it’s just way to soon to even be pregnant again. I’m starting to get scared cause I haven’t even had a period yet. Also I have a weird insane appetite. Do you think I could be? I haven’t even taken a pregnancy test since I lost the baby. People told me to track my hcg level back down to 0 but my pregnancy test I order on Amazon haven’t came in yet .
