Maybe a baby

do
I'm approx 9-10 dpo    Felt a little crampy about 2 days ago and light back ache.   Now I am super tired and feel bloated. Also I have been peeing like way more than normal.     Yes I know these r also period symptoms. But it's a bit early for me.   Normally I only feel those symptoms the day before my period.     Any hopes for a baby? 
UPDATE:  I've been using opk tests just to kinda see. This morning I had one that wasn't positive persay but was definitely darker than a negative
