Can you get a positive a day or so after a negative?

I’m currently 8 DPO, my period is due in 5 days. For the past week I’ve been nauseous, crampy, had clear CM, sporadic headaches, back aches, dull pain under my armpits, hip aches, blue veins on my breasts, jaw aches, felt fatigued, I’ve cried for the past 3 days in a row (not like me), and between 2 to 4 DPO I had a cold and sore throat. Three and two nights ago I had vivid dreams. I took a test first thing this morning (a First Response) and it came back negative. Should I take another one tomorrow or give it a few days? I’m trying not to symptom spot but it’s so hard!
