Pregnant? Can i still be pregnant?

I had 1 positive pregnancy test 2 months ago but the rest were negative my period was late that month , and lasted a few days the periods I’ve had after that I’ve experienced no pain, and the bleeding has last a couple of days, I went from having my period every month at the same time to this ,i feel. Pregnant and can feel light movement like i did with my first baby, im 8months pp just wondering is it possible for me to be pregnant and get negative tests and also bleed? I put the last positive pregnancy test to faulty but it was a clear blue test so im unsure how it would have been faulty !
