Ok I've been getting my period on the 25th of the month for as long as I can remember.And on August 1st I spotted bright red blood and it was only for a few hours.But then again on the 10th  I started with the same bright red blood and then turned to a reddish brown blood.And know it's been only two days and I have no blood. Could I be pregnant?? Someone please help me I'm so confused..
