Is it too soon for this to mean I'm pregnant?

Ugh, I'm moody, emotional, and just generally off feeling. 
I have 10 days until my period. According to glow I just finished my fertile window. We were extremely active for the past week. Like we've been screwing so much I'm tired and sore. 
But I've been an emotional wreck for two days. And a little tired. Going to bed early. And had some aching in on the left side of my pelvis. If I didn't know any better, I'd say AF was coming. But 10 days out is kinda early for pms symptoms for me. Even my husband asked if I was fixing to start my period because I've been a real piece of emotional mess. 
Y'all, is it too soon for this if I've conceived? I think my hopes are too high. But I just feel so crazy and emotional.
