Tested but..

I tested on the 1st because i didnt have a real period. It was a weird light period or else nothing,on and off for a couple days. I got a BFN and decided i just had an odd period. My boobs stopped hurting but i feel sick more and more after eating, i have lots of pressure down stairs, and my breasts have started to feel tight and sore again. I have started to need to pee all the time!! Should i test again or assume it was a weird period and let it go and retest again around 12DPO??
