Brittanie

On the 28th of December I had fertile cm

Figure I ovulated so I'm taking it as I'm 14dpo but still negitive pregnacy test

Tonight i cheaked my cm and had this

I think its fertile....i had some symptoms...cravings,peering a lot,headaches,slight cramps,also today i have toothpain not sure if its a pregnancy symptom or not.... So my question is could this be fertile cm... Is there a such thing as early pregnancy cm, if so is this it??
