ttc questions. CM and nausea

Hi All 
I'm really new to this community but thought it would be good to get others opinons.  I'm about 5dpo almost 6dpo.  I had 4 hours of nausea today.  Also a fair increase of creamy cm along with headaches.   I'm not sure if this could be too early for early pregnancy/implementation symptoms.  Hoping so but also don't want to risk getting my hopes up too high in case it isn't a positive sign.   Not due for my period until the 21.  I hate the period.  😓 
Thoughts?  Anyone else experience this?
