Should I test?

Hi everyone! 
My boyfriend and I are TTC.
My last "period" was March 10. My periods are always to the day and very heavy and last for 7 days. This time around I had 2 days of heavy bleeding, 1 light day and 2 days of barely spotting. I was nauseous and exhausted and my boobs hurt. I'm wondering if I should test? I tested 3 days before and had a BFN. When I was 18 and had gotten pregnant this same thing happened but i miscarried
