Pregnant women can have some light irregular bleeding during pregnancy, but it should not be like a ânormalâ period. Some women can confuse this for their period because often it can come right around the time she was expecting her normal period.The irregular bleeding or spotting that can occur during pregnancy is often a dark brown or a light pinkish color. It should not be enough bleeding to fill pads or tampons over a few days.If you are bleeding enough to fill pads and tampons, then this would be a good indication that you are probably not pregnant. negative result can mean that you are not pregnant, you took the test too early, or you took the test wrong. Pregnancy tests vary in their sensitivity (how soon they can detect the hormone hCG), and you may not have given your body enough time to produce enough hCG hormones that will show up on the test.
