Maybe I’m symptom searching...

So I had EWCM on cd 6 which was 2 days past my period. So hubby and I BD’d. I’m on CD 16 now, and usually would just be starting my fertile window, but I swear I’m feeling weird. I’ve been extra exhausted and lacking any motivation at work and napping when I get home and I think I felt nauseous this morning. I’ve had quite a bit of creamy CM since then and I even told my hubby that i feel off lately and i feel a bit more irritable than i normally am. I think I’m symptom searching because it would be crazy to have conceived on CD 6 even if I ovulated...
