Should i test?

Jessica
I had AF 5/7-13 and on the 21st and 22nd I had brown to light pink spotting not sure what it was never had it before. I have been very bloated with heartburn the best week and today I have had a backache my lower back for several hours. I helped my hubby clean out our spare room I didn't lift anything heavy but afterwards as I was doing dish I got nauseous, dizzy and my backache got worse. I'm not sure what's going on do you ladies think I should take a test even though I haven't missed my next AF yet. Been TTC for 8months so I'm scared to get bfn again.
