Help please !!!

I have been taking the digital ovulation test and they were all coming back negative. I finally started having some cramping and got the flashing smiley (high fertility) for 2 days. Monday morning I got my peak fertility and had all the signs of ovulation. Its only been 3 days and I am bleeding. I was just wondering if anyone else had this and still got pregnant ?!?! It's not constant. Only about an hour today but I feel like I see more spotting now. This is very stressful !!!
