12 dpo pregnancy symptoms?

Sarai

I am now currently 12dpo.

Was supposed to start my period 6 days ago, and still nothing.

Cervical mucus is clear with kind of a whitish tint.... Almost like watered down milk lol.

I have been super emotional.

My husband says I cry more than usual the last few days.

Mild cramps, and I have been very nauseous on and off for the past few days as well.

R these early signs of pregnancy??

We have been TTC 7 months
