I'm not concerned I'm pregnant I js couldn't find the right subject! My periods are ALWAYS the same I always bleed for around 4-5 days it starts heavy for one then goes light and I do get pains but only the first few days, and my blood is always a browny colour sum times read and I do get blood clots. This one has been very different I I have now Been on for 3 days it's still very heavy and it's bright red and I have really bad pains through the day is this a concern?
