Intense cramping 5 days PO

Dude. I’ve been feeling like crap since Monday. Monday and Tuesday, I had intense nausea. No other stomach symptoms. Then yesterday and today I’ve had cramping. Yesterday was very intermittent and a different kind of cramp than I feel with PMS. More of a sharp pain. Today it’s soooo much worse. It’s almost constant. It seems too early for PMS cramps. I just switched to this app from another app. That one has me at 5DPO. Flow has me at 2DPO so there’s a big discrepancy. Anyways, anyone have anything similar. I just feel crappy.
