Am I pregnant?

So I’ve been trying to conceive and well I’ve been having symptoms but I started bleeding. At first I thought it was implantation bleeding because it was light bleeding but then the second day it became heavy and now I’m on my third day and it’s lighter than usual, usually my periods are 4 to 5 days long the second and third day being the heaviest, I’ve taken two pregnancy test and they both came out negative. So far the people I’ve talked about this with thinks I’m pregnant. What should I do?
