Whatcha think?

I’m about a week away from my period and I’m usually not experiencing symptoms. But for the last few days I’ve felt nauseous, also have had a migraine since yesterday at noon, so roughly 36 hours now, excessively tired to where I just think about sleep at work, and my boobs are sore. I’ve had some lower left stomach cramping, and my discharge has been white and stretchy. Lower area near uterus is tender. Should I test now or hold out until my period is due?
