If you've taken more than one test and it came out negative, you're most likely not pregnant. But you CAN bleed during pregnancy. There's implantation bleeding, and some women also get their period even when they're pregnant. You might be so worried you're pregnant that you're getting the symptoms..kind of like a placebo. If things worsen, you may want to see a doctor. But most pregnancy tests are fairly accurate.

Negative results and bleeding mean you're not pregnant. However, since you don't believe that, go to a doctor and get a test and then get an ultrasound.
