I’m so confused

So

Okay so I’m sooo confused and I’m feeling nervous and kinda hopeless. I missed my period last month I’m thinking it was due to stress. So currently I’m 25 days late and I’m almost sure I ovulated this month because I used an OPK and I had some cramping on my left side but I’ve taken pregnancy test and all BFN😭😭😭 I’m 10dpo. Anyone have had a similar experience?
