Positive test but bleeding

Hi All, I just recently had 2 positive pregnancy tests. I’m super early in the pregnancy, would only be about 4 weeks. I went to the doctor to get my blood work done. I started having spotting yesterday which turned into light bleeding (enough that I need to wear a pad) with small little clots. I tested again today and received a negative test, but have read a false negative can show if there is bleeding present. Waiting on the doctor to call to confirm if I am pregnant or not. Has anyone else experienced this at all?
