12 DPO can I test now? What will it look like?

I am currently about 12 DPO give or take a day.

My Sypmtoms include! ->

Cramping

Dizziness

Headaches

fatigue

Feel like I'm "car sick"

My boobs feel like there are buruised not my usual tenderness before aunt flow

I was craving spicy food for a week! And I usually don't like spicy food

Couldn't sleep for the past 3 days 😭

When can I test?!?

If I test now should it be FMU only ?

Or should I wait till the day my period is due which is in 5 days?

If I test now what would my test look like? Faint?
