Pregnant? Light period, still not sure…

Patient: I am not sure if I’m pregnant. I was 8 days late, had taken a home test at 4 days late with a negative result, then had an extremely light, short period. I had severe nausea and breast tenderness, plus migraines which I rarely have, before the period. After the period, these all lessened but were and are still present, and the area around my uterus feels firm and very uncomfortable with any pressure one it, such as the elastic in my panties. I have had a previous pregnancy which resulted in miscarriage around 6.5 weeks. If I am pregnant now, I would be around 7 weeks. My mother thinks I may be pregnant as she had similar symptoms with my sister, including the light period. The more info I have, the better. What I would like to know is, should I take another test now or wait until I’ve missed my next period, and if I don’t miss my “period” but still think I may be pregnant, what then?
