Anxious to take a test!

It’s says that my next period is in six days? When I’m unsure exactly what day It ever comes, but last month it came on the 2nd . But it’s predicting it will come from the 1st-3rd of this coming month, my question is should I wait to take a test?

I have been feeling VERY moody , up and down all the time.

Head aches , cramping in the side on my back a few times last couple days , feeling sick to my stomach , stomach aches a lot too last couple days including some cramping .

randomly getting super warm. Last night I had a weird metallic taste in my mouth ( sides of my tongue)

I have been breaking out on my face a lot more Then usual.

I am not feeling myself at all ! I’m drained from the time I wake up till it’s time to go to bed !
