Am i pregnant or not??

Ishita
My next period is due, but i found that there is kind of spotting before 15 days of my periods.
Me and my husband had sex around 29th june'16 and since 2nd of july, i found my "P" bleeding little little every day. I did the pragnency test on 3rd july but it was negative. I also had vginal pain yesterday.
Am I pragnent or not??
