To test or not to test?

i’m around 7/8 DPO (although didn’t confirm O just went off of glow, pain and CM).. so i know it’s far too early to test but i’ve felt HORRIBLE for days.. like fluey and off. I just woke up from a nap and feel really nauseous and cramps. I’m concerned because i’m meant to be going out drinking tonight. Should i take a strip test just to put my mind at ease??
